The given chemical equation is:
On balancing the equation we get,
Calculating enthalpy of formation of this reaction from the standard heats of formation of the products and reactants:
Δ
=[(-1669.8kJ/mol)+ {3* (-909.27 kJ/mol)}]-[(-3442kJ/mol)+{3*(-285.8 kJ/mol)}]
=[(-4397.61kJ/mol)]-[(-4299.4kJ/mol)]
=-98.21kJ/mol
Total enthalpy change when 15 mol of reacts will be=
