1.)Calculate the change in entropy (in J/K) for the following reaction at 298 K:

C(s) + H2O(g) ? CO(g) + H2(g)

Use entropy for graphite (diamond is too expensive).

2.) Calculate the change in entropy (in J/K) for the following reaction at 298 K:

2NO(g) +O2(g) ? 2NO2(g)

Use the data in Appendix II (Tro); Appendix 4 (Zumdahl)

(When no amounts are given, it is for the reaction as written in moles. In this case 2 moles NO and 1 mole oxygen produce 2 moles NO2.)
