Explain the concentrations of a and b are initially the same

Reference no: EM13517651

A flask contains both A and B. Both decompose following first-order kinetics with half-lives of 50 and 18 minutes, for A and B respectively. If the concentrations of A and B are initially the same, how long will it take for the concentration of A to be four times of B?
