2A + 3B + C ⟶ D + E

The rate constant for this reaction is 0.25, and the reaction is second order in A and is first order in B and C.

Which option correctly gives the rate of the reaction if [A] is 0.4 M, [B] is 0.1 M and [C] is 0.2 M?

5.0 × 10–4
8.0 × 10–4
2.0 × 10–3
4.0 × 10–3

1 answer

rate = k(A)^2*(B)(C)
Substitute the numbers and solve for rate. Post your work if you get stuck.
