Test 1 question 1

Postby Katherine Jordak 1H » Tue Feb 13, 2018 10:33 pm

Hi,
I'm confused why in part A, the delta H of H2 is not included in finding the standard delta H of the rxn, but it is used in part B. I understand that standard delta H of H2 is zero, so we do we include bond enthalpy of H-H in part B?

Sorry, I meant to say why do we include bond enthalpy of H-H in part B?
