Question

what is the order of the reaction 2NO2(g) + F2(g) → 2NO2F(g)
please answer fast

Answer 1

The order in your rate law is always your products raised to the power of the stiochiometic coefficient that appears in the balanced chemical formula.

Answer 2

You have NO2 and F2 so the rate would be:

Because there's 2 moles of NO2 in our equation we raise it to the second power. And there's a 1 in F we raise that to the first power so the rate law is below .

r= k[NO2]^2[F2]

This would be a third order reaction because we add the exponents 2+1 and the reaction is second order with respect to NO2 and first order with respect to F2 however you would need to verify this experimentally
