Neco Model Questions Vol1 2017 Chemistry Question 24
Practice objective / multiple choice question 24 from the 2017 Neco Model Questions Vol1 Chemistry examination.
Given that the standard enthalpy change for the reaction \(\mathrm{N_2(g) + O_2(g) \rightarrow 2\,NO(g)}\) is +180.5 kJ, the standard enthalpy of formation of \(\mathrm{NH_3(g)}\) is -46.1 kJ·mol⁻¹, and that of liquid water \(\mathrm{H_2O(l)}\) is -285.8 kJ·mol⁻¹, calculate the standard enthalpy change for the combustion of ammonia: \(\mathrm{4\,NH_3(g) + 5\,O_2(g) \rightarrow 4\,NO(g) + 6\,H_2O(l)}\).
