An intermediate reaction used in the production of nitrogen-containing fertilizers is the between ammonia and oxygen
4NH3(g) + 5O2(g)=4NO(g) +6H20(g)
A 150.0 L reaction chamber is charged with reactants to subsequent partial pressures at 500oC:P(NH3) =1.3 ATM,P(O2) =1.5ATM. Explain what is the limiting reactant?
