Step-by-step explanation:
The mechanism of the reaction is;
Step 1 (slow)
NO2(g) + F2(g) -------> NO2F(g) + F(g)
Step 2 (fast)
NO2(g) + F(g) -----> NO2F(g)
Overall reaction;
2NO2(g) + F2 (g) ------> 2NO2F(g)
a) Hence both steps 1 and 2 are bimolecular, two reacting species were involved.
b) Overall reaction;
2NO2(g) + F2 (g) ------> 2NO2F(g)
c) The intermediate in this reaction is F (g), notice that it does not appear in the final reaction equation.
