The integrated rate law allows
chemists to predict the reactant concentration after a certain
amount of time, or the time it would take for a certain
concentration to be reached. The integrated rate law for a
first-order reaction is: [A]=[A]0e−kt Now say we are particularly
interested in the time it would take for the concentration to
become one-half of its initial value. Then we could substitute
[A]02 for [A] and rearrange the equation to: t1/2=0.693k This
equation calculates the time...

The reaction A + 2B → C proceeds according to the rate law, rate = k[A][B] with k = 6.05 x 10-3 M-1 min-1. Assume that at the start of a particular reaction, [A] = 0.275 M, [B] = 0.0950 M. What is the initial rate of reaction? What is the rate when half of B has reacted? Give units! [Remember: ln(ab) = ln(a) + ln(b)]
