The commercial production of "water gas" utilises the endothermic reaction c(s)+h2o(g)=h2(g)+co(g) the heat required for this reaction is generated by combustion of coal to CO2 using stoichiometric amount of air.(79%N2 by volume and 21%O2 by volume).The superheated steam undergoes 75%conversion.Using the following data answer : enthalpy of formation of CO(g)=-110.53kJ/mol ;enthaply of formation of H2O(g)=-241.81kJ/mol ;enthalpy of formation of CO2(g)=-314.0kJ/mol
(A)The amount of heat liberated when one litre of product gases are burnt at 373 k and 1 atm is:
