Answer 1

Answer:

constant pressure

Explanation:

tinks so

Answer 2

Explanation:

option (b) is correct...

that is constant volume

At constant volume, the heat of reaction is equal to the change in the internal energy of the system. At constant pressure, the heat of reaction is equal to the enthalpy change of the system.
