A complex reaction takes place in 2 steps (i) $\mathrm{NO}_{2(\mathrm{~g})}+\mathrm{F}_{2(\mathrm{~g})} \rightarrow \mathrm{NO}_2 \mathrm{~F}_{(\mathrm{g})}+\mathrm{F}_{(\mathrm{g})}+$ (slow) (ii) $\mathrm{F}_{(\mathrm{g})}+\mathrm{NO}_{2(\mathrm{~g})} \rightarrow \mathrm{NO}_2 \mathrm{~F}_{(\mathrm{g})}($ fast $)$ Identify the reaction intermediate?
  1. $\mathrm{F}_{(\mathrm{g})}$
  2. $\mathrm{NO}_{2(\mathrm{~g})}$
  3. $\mathrm{F}_{2(\mathrm{~g})}$
  4. $\mathrm{NO}_2 \mathrm{~F}_{(\mathrm{g})}$

Solution

Reaction intermediates are those substance which are formed in one step and get consumed in the successive step $\therefore$ In the given mechanism it is $\mathrm{F}(\mathrm{g})$
