Use hess’s law to calculate the standard heat of the water-gas shift reactions. co(g) + h2o àco2(g) + h2from each of the two sets of data given here: (a)co(g) + h2o(l) àco2(g)+ h2(g)∆퐻#r = 1226 btu/lb-moleh2o(l) àh2o(v)∆퐻#r = 18,935 btu/lb-mole(b)co(g) + ½ o2(g)àco2(g) ∆퐻#r = -121,740 btu/lb-moleh2(g)+ ½ o2(g)àh2o(v)∆퐻#r = -104,040 btu/lb-mole
