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?

8.0x10⁻⁴ M/s

Explanation:

The rate of the reaction is given by the equation:

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

b is the correct answer
