In a endothermic reaction,

A. There is no change in temperature, but there is a change in state
B. The temperature of the products is higher than the temperature of reactants
C. The temperature of the products is lower than the temperature of the reactants
D. The temperature of the products is the same as the temperature of the reactants

C. The temperature of the products is lower than the temperature of the reactants

In an endothermic reaction, energy is absorbed from the surroundings, causing the temperature of the products to be lower than the temperature of the reactants.
