# In the reaction,$4NH_3+5O_2\rightarrow 4NO+6H_2O$ when one mole of ammonia and one mole of oxygen are made to react completely then
$\begin{array}{1 1}(a)\;\text{1.0 mole of NO is formed}\\(b)\;\text{all oxygen is consumed} \\(c)\;\text{1.0 mole of }H_2O\text{ is produced}\\(d)\;\text{all ammonia is consumed}\end{array}$
