    Rate equation for the reaction is as follows

    Rate = k [A]³[B]²

    concentration of A = 2 M

    concentration of B = 3 M

    k - rate constant - 0.01

    as this is a 5th order reaction, units for rate constant are M⁻⁴s⁻¹

    substituting these values in the equation

    Rate = k [A]³[B]²

    rate = 0.01 M⁻⁴s⁻¹ x (2 M) ³ x (3 M) ²

    rate = 0.01 x 8 x 9 = 0.72

    rate of the reaction is 0.72 M/s
