## Which change causes the equilibrium to shift to the right?

According to Le Chatelier’s principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products. By the same logic, reducing the concentration of any product will also shift equilibrium to the right.

## Which quantities must be equal for a chemical reaction at equilibrium?

Which two factors must be equal when a chemical reaction reaches equilibrium? The rate of the forward reaction and the rate of the reverse reaction.

## Which statement is always correct for a chemical reaction at equilibrium?

In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.

## How do you know when a system has reached equilibrium?

Q can be used to determine which direction a reaction will shift to reach equilibrium. If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.

## Why does equilibrium constant change with temperature?

Increasing the temperature decreases the value of the equilibrium constant. Where the forward reaction is endothermic, increasing the temperature increases the value of the equilibrium constant. So, according to Le Chatelier’s Principle the position of equilibrium will move to the left.

## What happens to equilibrium when pressure is increased?

According to Le Chatelier’s principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas. This particular reaction shows a total of 4 mol of gas as reactants and 2 mol of gas as products, so the reaction shifts toward the products side.

## What is the equilibrium constant for the reverse reaction?

The equilibrium expression written for a reaction written in the reverse direction is the reciprocal of the one for the forward reaction. K’ is the constant for the reverse reaction and K is that of the forward reaction.

## Which two factors must be equal when a chemical reaction reaches equilibrium?

(1) The concentrations of the products and reactants are equal. (2) The concentrations of the products and reactants are constant. (3) The rate of the forward reaction is less than the rate of the reverse reaction. (4) The rate of the forward reaction is greater than the rate of the reverse reaction.

## How do you calculate the equilibrium constant?

Write the equilibrium expression for the reaction. Determine the molar concentrations or partial pressures of each species involved. Determine all equilibrium concentrations or partial pressures using an ICE chart. Substitute into the equilibrium expression and solve for K.

## What will happen when at a constant temperature more iodide ions I are added to the equilibrium below?

The higher temperature increases the rate of both reactions but the reverse reaction is affected more than the forward. What will happen when at a constant temperature, more iodide ions, I-, are added to the equilibrium below? The amount of solid iodine decreases and the equilibrium constant increases. B.

## Which statement is correct for a crystal of iron II sulfate in a state of equilibrium with a saturated solution of iron II sulfate?

Which statement is correct for a crystal of iron(II) sulfate in a state of equilibrium with a saturated solution of iron(II) sulfate? The color of the solution does not change but the shape of the crystal may change.

## Which change will Favour the reverse reaction in the equilibrium?

An increase in temperature caused the concentration of the product to decrease and the concentrations of the reactants to increase. This means that the reverse reaction has been favoured. An increase in temperature will favour the reaction that takes heat in and cools the reaction vessel (endothermic).

## What is equilibrium and example?

An example of equilibrium is in economics when supply and demand are equal. An example of equilibrium is when you are calm and steady. An example of equilibrium is when hot air and cold air are entering the room at the same time so that the overall temperature of the room does not change at all.

## What is an equilibrium equation?

The equilibrium equation describes the static or dynamic equilibrium of all internal and external forces of the system. In the static case, the equilibrium equation is. [6.23] where K is the stiffness matrix of the system, u is the vector with the nodal displacements and F represents the external forces (Fig. 6.11).

#### The equation of exchange can be stated as

What is the equation of exchange equal to? So the equation of exchange says that the total amount of money that changes hands in the economy will always equal the total money value of the goods and services that change hands in the economy. So now the equation of exchange says that total nominal expenditures […]

#### Calcium and water balanced equation

What happens when calcium reacts with water? After a second or so, the calcium metal begins to bubble vigorously as it reacts with the water, producing hydrogen gas, and a cloudy white precipitate of calcium hydroxide. What is the balanced equation for calcium oxide and water? CaO(s) + H2O (l) → Ca(OH)2(s) This reaction occurs […]
