I really don't know how to do this question
i don't understand what this question is asking
a) i think the amount of heat released is same as heat of formation of H2O = 285.9 kJ mol but i think i am wrong
b) i don't know how to calculate the electrical work, Is it related to free energy?
c) omg, heat again, same ans ? =(

plz help me ><

Question 4 is not the question which i don't understand, only question 3
Question 3 is a energy question, but i found it is quiet tricky

part a) I think the equation for direct combustion is 1/2 O2(g) + H2(g) --> H2O (l) which is same as the equation for the "heat of formation of water", it is -285.9kJ mo1-1 ?
part b) non expansion work = change of G ? i really don't know as my professor didn't tell us, but i found some data on the internet said it is true.

part c) amount of heat released ? is it the same as part a? both are the heat released

and also pleases del my old post , thank you

ΔG⁰ is the work done here
and I also feel that heat released will be same as in a part
