Solution

The correct option is B False
When temperature of an endothermic reaction is increased, the reaction will proceed in the forward direction so as to absorb heat and nullify the effect of increasing temperature. This will increase the value of the equilibrium constant $K_{c}$ and increase the yield of the reaction.
