Question

Calculate the standard enthalpy of formation of ammonia gas (NH3) using the following information:- Standard enthalpy of formation for nitrogen gas (N2) = 0 kJ/mol- Standard enthalpy of formation for hydrogen gas (H2) = 0 kJ/mol- Standard enthalpy of formation for ammonia gas (NH3) = -46 kJ/mol

Answer 1

The standard enthalpy of formation for ammonia gas  NH3  is already given in the information provided. It is -46 kJ/mol. There is no need for further calculation.
