3.12 From standard enthalpies of formation, standard entropies, and standard heat capacities
available from tables in the Data section, calculate the standard enthalpies and entropies at 298 K
(g)→CO(g) + H
and 398 K for the reaction CO
(g) + H
O(g). Assume that the heat capacities are
2
2
2
constant over the temperature range involved.
