Gibbs free energy question
« on: May 05, 2020, 09:13:32 AM »
Hello i just wanted clarification from someone who is used to doing thermochemistry questions. I dont want to know the answer to the quiestion attatched, i just wanted to know how can i get the values for the ∆fG. Does the question expect me to look off a standard free energies of formation table or is there a calculation i can do to find these values.

It's also conceivable that the fuel cell exploits only the oxidation of hydrogen, not carbon. The stories with semi-permeable membranes would support that, and I have such memories in my head.

Does the question tell more about it?
