Rate Constant Chemistry?

What is the rate constant for a second order reaction when the initial [A] = 0.20M, the initial [B] = 0.86M and the initial rate = 0.0900 M/s?

Best Answer - Chosen by Voters

For the second order reaction, the rate equation is

rate = k [A] [B]
substitute the values given,

0.09 = k( 0.2) ( 0.86 )

solve for k.
