Vedclass · Accepted Answer

$2 NO_2(g) + F_2(g) \rightarrow 2NO_2F(g)$

Vedclass · Answer

(C) Step $1$: Analyze the rate laws for the given reactions.Step $2$: The reaction $2 NO_2(g) + F_2(g) \rightarrow 2NO_2F(g)$ follows the rate law $Rate = k[NO_2][F_2]$. This is a second-order reaction (first order with respect to $NO_2$ and first order with respect to $F_2$, total order $1+1=2$).Step $3$: $2 H_2O_2(l) \rightarrow 2H_2O(l) + O_2(g)$ is a first-order reaction.Step $4$: $CH_3CHO(g) \rightarrow CH_4(g) + CO(g)$ is a fractional order reaction (order $1.5$).Step $5$: $2 NO(g) + 2H_2(g) \rightarrow N_2(g) + 2H_2O(l)$ is a third-order reaction.Step $6$: Therefore, option $C$ is the correct answer.

$[A_2]_0$	$[B_2]_0$	Initial rate of formation of $AB$ $(mol \ L^{-1} s^{-1})$
$0.1 \ M$	$0.1 \ M$	$2.5 \times 10^{-4}$
$0.2 \ M$	$0.1 \ M$	$5.0 \times 10^{-4}$
$0.2 \ M$	$0.2 \ M$	$1.0 \times 10^{-3}$

Experiment	$[A] / mol \, L^{-1}$	$[B] / mol \, L^{-1}$	Initial rate of formation of $D / mol \, L^{-1} \, min^{-1}$
$I$	$0.1$	$0.1$	$6.0 \times 10^{-3}$
$II$	$0.3$	$0.2$	$7.2 \times 10^{-2}$
$III$	$0.3$	$0.4$	$2.88 \times 10^{-1}$
$IV$	$0.4$	$0.1$	$2.40 \times 10^{-2}$
