How much heat energy (in kj) will be absorbed or released if 11.5 grams of ammonia is produced? State whether the energy will be absorbed or released?
Homework Answers
Haber process, energy released.
N2(g) + 3H2(g) <----> 2NH3(g) DH0 = -91.8 kj
2 mol NH3 formation gives 91.8 kj energy.
no of mol of NH3 = 11.5/17 = 0.676 mol
Amount of energy released = 0.676*91.8/2 = 31.03 kj
