Question

5 Consider a 70% efficient hydrogen-oxygen fuel cell working under standard conditi 298 K. Its cell reaction is 1 H2(g) + 302 (g) → H20 (1). ( The work derived from the cell on the consumption of 1.0 x 10-3 mol of H2(g) is use 1.00 mol of a monoatomic ideal gas in a thermally insulated container. What is the temperature (in K) of the ideal gas? The standard reduction potentials for the two half-cells are given below. W 02(g) + 4H+(aq) + 4e → 2 H2O (1), E° = 1.23 V, 2H+(aq) + 2e → H2 (g), E° = 0.00 V. Use F = 96500 C mol-1, R = 8.314 J mol-? K-1.
