$CH_3CHO + HCN \to CH_3CH(OH)CN \xrightarrow{H-OH} CH_3CH(OH)COOH$
$2H_2 + 2NO \to N_2 + 2H_2O$
the following mechanism has been proposed
$(i)$ $2NO \rightleftharpoons N_2O_2\,$ (fast)
$(ii)$ $N_2O_2 + H_2 \xrightarrow{{{k_2}}} N_2O + H_2O\,$ (slow)
$(iii)$ $N_2O + H_2 \to N_2 + H_2O\,$ (fast)
then what will be the rate law of this reaction ?
