Question

write relationship between heat of reaction at constant pressure that constant volume​

Answer 1

⠀⠀ ⠀ ⠀⠀ $\huge{\tt{\red{❥}\green{A}\purple{N}\pink{S}\blue{W}\orange{E}\red{R}}}$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.

Answer 2

Answer:

For an ideal gas at constant pressure, it takes more heat to achieve the same temperature change than it does at constant volume. At constant volume all the heat added goes into raising the temperature. At constant pressure some of the heat goes to doing work.
