2. (5 points) Use Hess's law to calculate the standard heat of the water-gas shift reaction CO(g)+H2O(v)CO2(g)+H2(g) from each of the two sets of data given here: CO(g)+H2O(l)CO2(g)+H2(g):H2O(l)H2O(v):H^ro=+1226Btu/lbmoleH^v=+18935Btu/lbmole a) b) CO(g)+21O2(g)CO2(g):H^ro=121,740Btu/lb-moleH2(g)+21O2(g)H2O(v):H^ro=104,040Btu/lbmole
