Answer: The correct answer is [tex]k[NO_2][F_2][/tex]
Explanation:
Rate law states that the rate of a reaction is directly proportional to the concentration of the reactants each raised to power a stoichiometric coefficient which is determined experimentally and is called as order.
[tex]Rate=k[A]^x[B]^y[/tex]
where,
k = Rate constant
x = Order with respect to A
y = Order with respect to B
In a mechanism, it is determined from the slow step of the reaction.
The slow step of the mechanism is:
[tex]NO_2+F_2\rightarrow NO_2F+F[/tex]
The rate of this reaction is given by the expression:
[tex]rate=k[NO_2][F_2][/tex]
Thus, the correct answer is [tex]k[NO_2][F_2][/tex]
