The reaction described by the equation 2A+B+2C products is first order in A, first order in B, and second order in C with a rate constant of k = 2.63 M3 S1. The reaction was started with [A] = 3.25 mM, [B]o = 34.2 μM, and [C] = 47.2 mM. How long does it take for the concentration of B to decay to 20.0 μM? (Hint: Use a pseudo rate law to solve the question.) Define variables, solve symbolically (show work!), then obtain the numerical result (show work!). Use units where appropriate in all steps of your calculation.
