Consider the mechanism given below derived from spectrochemical analysis of the reaction between NO and $\mathrm{F_2}$:
$\mathrm{NO + F_2 \longrightarrow NOF_2}$ (slow step)
$\mathrm{NOF_2 + NO \longrightarrow 2NOF}$ (fast step)
The overall reaction is:
$\mathrm{2NO + F_2 \longrightarrow 2NOF}$
Write the rate law for this reaction.
Answer
Answer
AIRate $= k[\mathrm{NO}][\mathrm{F_2}]$
The rate is decided by the slow step, $\mathrm{NO + F_2 \longrightarrow NOF_2}$.
