(d) what is the standard potential for half-cell reaction (A) obtained in part (c)?

(e) what is the numerical value of the equilibrium constant K for the overall reaction?

(f) Solve part (c) for the concentrations of the 4 species. Hint: if K is very different from unity, some terms in the mass-action law may be neglected.

10.12 The electrochemical cell shown below converts hydrogen and oxygen to water and drives a motor in the process. The electrode conditions are: anode: pH =5; pH2 = 1 atm; cathode: pH = 4; pO2 = 1 atm.

(a) Write the half-cell reactions for the anode and cathode and the corresponding Nernst equations

(b) What is the cell voltage?

(c) How much work is done by the motor per mole of water produced?

(d) How much heat is released per mole of water produced?

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
