Utilize the subsequent data compute the heat of reaction for the production of coal gas- 2 C(s) + 2 H2O(g) CH4(g) +CO2(g)C(s) + H2O(g) = CO(g) + H2(g) Standard Heat of reaction =+131.3 kJ/molCO(g) + H2O(g) = CO2(g) + H2(g) Standard Heat of reaction = -41.2 kJ/molCO(g) + 3 H2(g) = CH4(g) + H2O(g) Standard Heat of reaction = -206.1 kJ/mol
