Reaction: 2B ---> 4 C

This reaction exhibits a half-life of 11.5 minutes at 60 C when [B]0 = 0.33M.

a) What is the rate constant for the reaction if the rate law for the reaction is R= k [B]?

b) What is the half-life of the reaction if the reaction is second order and [B]0 = 0.57 M?

K = 0.0603

c) Assuming the reaction is first order and you started with [B]0 = 0.33M, what concentration of C would be produced after 8.0 minutes?

    The half-life of a reaction, t1/2, is the time it takes for the reactant concentration [A] to decrease by half. For example, after one half-life the concentration falls from the initial concentration [A]0 to [A]0/2, after a second half-life to [A]0/4, after a third half-life to [A]0/8, and so on. on. For a first-order reaction, the half-life is constant. It depends only on the rate constant k and not on the reactant concentration. It is expressed as t1/2=0.693k For a...
