Why does K value change with temperature?

A temperature increase favors the side that is higher on the graph. In an endothermic reaction, the higher side is the products, so K will increase. In an exothermic reaction, the higher side is the reactants, so K will decrease.

How does K vary as temperature increases does K increase/decrease or remain constant?

You can see that as the temperature increases, the value of Kp falls. This is typical of what happens with any equilibrium where the forward reaction is exothermic. Increasing the temperature decreases the value of the equilibrium constant.

Why is K temperature dependent?

The rate constant, k, relates the concentrations and orders of the reactants to the reaction rate. It is dependent on the reaction as the temperature at which the reaction is performed.

How does temperature affect equilibrium constant K?

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. If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again.

What happens to K when temperature increases endothermic reaction?

If Kc decreases with an increase in temperature, the reaction shifts to the left. If Kc increases with an increase in temperature, the reaction to shifts to the right. If the reactants dominate in a reaction, then K< 1. The smaller the K value, the more the reaction will tend toward the left.

What changes occur when the temperature of the system is decreased?

A decrease in temperature shifts the reaction to the product side. In an endothermic reaction, heat is absorbed by the reaction, so an increase in temperature will shift to the product side. A decrease in temperature for an endothermic reaction will shift to the reactant side.

Why does decreasing the temperature decrease the rate of reaction?

When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. When you increase the pressure, the molecules have less space in which they can move. That greater density of molecules increases the number of collisions.

How does temperature change affect equilibrium?

Increasing the temperature decreases the value of the equilibrium constant. If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again. It will do that by favoring the reaction which absorbs heat.
