Problem

At a certain temperature and pressure, 45.0 L of hydrogen gas reacts completely with 15.0 L of nitrogen gas to produce 30.0 L of ammonia gas. Which balanced equation is most consistent with these volumetric data? a) N2+2H2  →  2NH3\mathrm{N_2 + 2 H_2 \; \rightarrow \; 2 NH_3} b) 2 N2+6 H2  →  4 NH3\mathrm{2\,N_2 + 6\,H_2 \; \rightarrow \; 4\,NH_3} c) N2+3H2  →  2NH3\mathrm{N_2 + 3 H_2 \; \rightarrow \; 2 NH_3} d) 2 N2+3 H2  →  2 NH3\mathrm{2\,N_2 + 3\,H_2 \; \rightarrow \; 2\,NH_3}
