Chapter 5, Problem 71QAP

An intermediate reaction used in the production of nitrogen-containing fertilizers is that between ammonia and oxygen:

$4{\text{NH}}_3\left(g\right)+5{\text{O}}_2\left(g\right)\to 4\text{NO}\left(g\right)+6{\text{H}}_2\text{O}\left(g\right)$

A 150.0-L reaction chamber is charged with reactants to the following partial pressures at 500°C:

$P_{{\text{NH}}_3}=1.3$atm, $P_{{\text{O}}_2}=1.5$atm. What is the limiting reactant?
