Solution

The correct option is C Its value may increase or decrease with increase in temperature
Increase in the temperature decreases the value of equilibrium constant because forward reaction is exothermic.
When the forward reaction is endothermic increase the temperature increases the value of equilibrium constant.
These occurs when chemical equilibria shifts toward the products or reactants.
