Answer:

See explanation

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.
