### Change in H is equal to Q

On page 253 of the textbook, it states, "At constant pressure, and with no nonexpansion work: change in H is equal to q." Where did that equation come from?

### Re: Change in H is equal to Q

It is the definition of enthalpy: $\Delta H=q_{p}$

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
