Question

what is the limiting reactant and the theoretical yield for both A and B (in grams)

A) 1.25 moles of N2 and 3.65 moles of H2

B) 44.0 grams of N2 and 3.00 moles of H2

Answer 1

> 2NH3 A) Equati on: N2 +3H2 2 mol NH produced from N 1.25 mol N2 x- No of moles of NH 1 mol N = 2.50 mol N2 2 mol NH3 3 mol H produced from H 3.65 mol H2 x- No of moles of NH = 2.43 mol H Since H2 limits the production of NH3, H2 acts as the limiting reactant. No of moles of NH3 produced 2.43 mol NH 17.04 g 2.43 mol NH3x theoretical yiled of NH 1 mol NH3 = 41.5 g 2NH3 B) Equati on: N2 +3H2 2 mol NH3 1 mol N 1molN2 28.02 g 44.0 gx. X produced from N No of moles of NH = 3.14 mol NH3 2 mol NH3 3 mol H2 produced from H, = 3.00 mol H2x- No of moles of NH 2.00 mol H Since H2 limits the production of NH3, H2 acts as the limiting reactant. No of moles of NH3 produced 2.00 mol NH 17.04 g = 2.00 mol NH3X theoretical yiled of NH 1 mol NH3 34.1 g
