Change of heat content when one mole of compound is burnt in oxygen at constant pressure is called the

A Calorific value
B Heat of reaction
C Heat of combustion
D Heat of formation

Correct Answer: Heat of combustion

Heat of combustion is the change in heat content of the compound when one mole of that compound is burnt in the presence of oxygen. This type of reaction is where common in petroleum refinery where coke is combusted and removed.
