Ammonia and oxygen reacts at higher temperatures as `4NH_(3)(g) + 5O_(2)(g) rarr 4NO(g) + 6H_(2)O (g)` In an experiment, the concentration of NO increases by `1.08 xx 10^(–2)" mol litre"^(–1)` in 3 seconds. Calculate.
(i) rate of reaction.
(ii) rate of disappearance of ammonia
(iii) rate of formation of water.

Explanation

To solve the problem step by step, we will follow the stoichiometry of the reaction and the information given in the question.

### Given Reaction:
\[ 4NH_3(g) + 5O_2(g) \rightarrow 4NO(g) + 6H_2O(g) \]

### Given Data:
- Increase in concentration of \( NO \) = \( 1.08 \times 10^{-2} \, \text{mol L}^{-1} \) in \( 3 \, \text{s} \)
