how do you solve this problem?

consider the reaction
A->B
the rate of the reaction is 1.6 x 10^-2 M/s when the concentration of A is 0.35 M. Calculate the rate constant if the reaction is a) first order in A and b) second order in A.

  • chemistry -

    rate of reaction = k(A)x where x is the order of the reaction.
    For part a).
    R = k(A)
    1.6 x 10^-2 = k(0.35). Solve for k.

    For part b).
    R = k(A)2
    1.6 x 10^-2 = k(0.35)2. Solve for k.
