The reaction of cyanamide, NH2CN(s) with oxygen was run in a bomb calorimeter and ΔU at 300 K was found to be - 743 kJ mol-1. The value of ΔH at 300 K for the combustion reaction:
NH2CN(s) + \(\frac{3}{2}\)O2(g) → N2(g) + CO2(g) + H2O(l) would be:
- - 741.75 kJ mol-1
- - 743 kJ mol-1
- - 744.25 kJ mol-1
- - 740.5 kJ mol-1
Answer
(C) - 744.25 kJ mol -1
