In certain areas where coal is cheap, artificial gas is produced for household use by the 'water gas' reaction C(s) + H_2O(g) overset(600^@C)(to) H_2(g) + CO(g) Assuming that coke is 100% carbon, calculate the maximum heat obtainable at 298 K from the combustion of 1.0 kg of coke and compare this value to the maximum heat obtainable at 298 K from burning the water gas produced from 1.0 kg of coke. Heat of combustion of C, H_2 and CO are -94.1, -68.4 and -68.0 kcal/mole respectively.
