ICF for the reaction:
N2 + 3 H2 ⇌ 2 NH3
I 2.6 mol + x 3.6 mol + 3x 0
C -x -3x +2x
F 2.6 mol 3.6 mol 2.6 mol
A mixture of N2 (g) and H2 (g) reacts in a closed container to form ammonia, NH3 (g). The reaction ceases before either reactant has been totally consumed. At this stage 2.6 mol N2, 2.6 mol H2, and 2.6 mol NH3 are present.
How many moles of N2 and H2 were present originally?
