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.

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.
