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?

Answer:

8.0x10⁻⁴ M/s

Explanation:

The rate of the reaction is given by the equation:

[tex]-r =k* [A]^x*[B]^y*[C]^z[/tex]

Where the minus signal indicates that the reactants are disappearing, k is the constant of the reaction, and x, y, and z are the orders of each compound.

-r = 0.25*(0.4)²*(0.1)*(0.2)

-r = 8.0x10⁻⁴ M/s
