(A) For the reaction $4 NH_{3(g)} + 5 O_{2(g)} ightarrow 4 NO_{(g)} + 6 H_2O_{(g)}$,the rate expression is given by: $-\frac{1}{4} \frac{d[NH_3]}{dt} = -\frac{1}{5} \frac{d[O_2]}{dt} = +\frac{1}{4} \frac{d[NO]}{dt} = +\frac{1}{6} \frac{d[H_2O]}{dt}$ Given that the rate of formation of $NO$ is $\frac{d[NO]}{dt} = 3.6 	imes 10^{-3} \ mol \ L^{-1} \ sec^{-1}$. Equating the terms for $NO$ and $H_2O$: $\frac{1}{4} \frac{d[NO]}{dt} = \frac{1}{6} \frac{d[H_2O]}{dt}$ $\frac{d[H_2O]}{dt} = \frac{6}{4} 	imes \frac{d[NO]}{dt} = 1.5 	imes 3.6 	imes 10^{-3} \ mol \ L^{-1} \ sec^{-1}$ $= 5.4 	imes 10^{-3} \ mol \ L^{-1} \ sec^{-1}$

Ammonia and oxygen react at high temperature as in the reaction,$4 NH_{3(g)} + 5 O_{2(g)} \rightarrow 4 NO_{(g)} + 6 H_2O_{(g)}$. If the rate of formation of $NO$ is $3.6 \times 10^{-3} \ mol \ L^{-1} \ sec^{-1}$,calculate the rate of formation of water.
