CHE103 Thermochemistry Examples 1.) Determine Δ rxn Hº for the following reaction: CH 3 CO 2 H ( l ) + CH 3 OH ( l ) CH 3 CO 2 CH 3 ( l ) + H 2 O ( l ) Given the following Δ rxn Hº values: [A] CH 3 CO 2 H ( l ) + 2 O 2 (g) 2 CO 2 (g) + 2 H 2 O ( l ) Δ rxn Hº = -875.2 kJ/mol-rxn [B] 2 CH 3 OH ( l ) + 3 O 2 (g) 2 CO 2 (g) + 4 H 2 O ( l ) Δ rxn Hº = -1451.4 kJ/mol-rxn [C] 2 CH 3 CO 2 CH 3 ( l ) + 7 O 2 (g) 6 CO 2 (g) + 6 H 2 O ( l ) Δ rxn Hº = -3184.4 kJ/mol-rxn {answer: -8.7 kJ/mol-rxn } { the desired reaction is [A] + [B]/2 [C]/2 } 2. ) Calculate Δ rxn Hº for this reaction of hydrazine with nitrogen dioxide:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
