Question

heat exchange at constant pressure is equal to
(a)W
(b)∆H
(c)∆U
(d)∆S​

Answer 1

Explanation:

$\huge\tt\underline\red{✨\:Answer\:✨}$

(b) ∆H

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.
