Enter your answer in the provided box.

A flask contains a mixture of compounds A and B. Both compounds decompose by first-order kinetics. The half-lives are 77.00 min for A and 18.00 min for B. If the concentrations of A and B are equal initially, how long will it take for the concentration of A to be four times that of B?

Answer #1

So we can find out the rate constant from the half life.

And after determination of rate constant we can easily calculate the time at which the A is 4 times the B.
