A) enthalpy of reaction
B) enthalpy of fusion
C) enthalpy of combustion
D) enthalpy of formation
Correct Answer: A
Solution :
Since the given reaction is a balanced chemical reaction, the enthalpy change occurring during the reaction is called enthalpy of reaction \[({{\Delta }_{r}}H)\]. (Remember, here the enthalpy change cannot be said enthalpy of combustion because two moles of \[CO\]are used while heat of combustion is the heat liberated when one mole of a substance undergoes combustion in excess of oxygen.)
