Chapter 17, Problem 124AE

The overall reaction and equilibrium constant value for a hydrogen-oxygen fuel cell at 298 K is

$\begin{array}{cc}2{\text{H}}_{\text{2}}\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)\to 2{\text{H}}_{\text{2}}\text{O}\left(l\right)& K=1.28\times {10}^{83}\end{array}$

a. Calculate  and ∆G° at 298 K for the fuel cell reaction.

b. Predict the signs of ∆H° and ∆S° for the fuel cell reaction.

c. As temperature increases, does the maximum amount of work obtained from the fuel cell reaction increase, decrease, or remain the same? Explain.
