Answer 1

Equation: N, + 3H, — 2NH, 2 mol NH, No of moles of NH, produced from N, =0.200 mol N,x= mong 1 mol N, = 0.400 mo N 2 mol NHÀ No of moles of NH; produced from H2 = 0.656 mol H, 23 mol H, = 0.437 mol H Since N, limits the production of NH3, N, acts as the limiting reactant, Thus, no of moles of NH, gas produced is 0.400 mol NH; Since N, is the limiting reactant, it reacts completely and the no of moles of N, remains would be 0 mol N, No of moles of H, present initially = 0.656 mol H, No of moles of H, reacted=0.200 mol N, X - 1 mol N = 0.600 mol H2 No of moles of H, left out = 0.656 mol -0.600 mol = 0.056 mol
