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:
$\mathrm{2NO + F_2 \longrightarrow 2NOF}$
What is the overall order of this reaction?
Answer
Answer
AIOverall order $= 1 + 1 = 2$ (second order), from rate $= k[\mathrm{NO}][\mathrm{F_2}]$.
