When a reaction takes place at constant pressure, the heat transferred is equal to the Question 2 options:

A)

energy of reaction.

B)

enthalpy of reaction.

C)

mass of reaction.

D)

entropy of reaction.

At constant pressure, the heat of reaction is equal to the enthalpy change of the system. Most chemical reactions occur at constant pressure, so enthalpy is more often used to measure heats of reaction than internal energy
