Two substances A and B are present such that `[A_(0)]=4[B_(0]` and half-life of A is 5 minutes and that of B is 15 minutes. If they start decaying at the same time following first order kinetics after how much time the concentration of both of them would be same ?

Two substances A and B are present such that [A]=： 4 [B] and half life of A is 5 minute and of B is 15 minute. If they start decaying at the same time following first order, how much time later will the concentration of both of them would be same

Two substance A and B are present such that [A]=4[B} and half life of A is 5 minutes and of B is 15 minutes. If they start decaying at the same time following first order, how much time later will the concentration of both of them would be the same?

Two reacants A and B are present such that [A_(0)] = 4[B_(0)] and t_(1//2) of A and B are 5 and 15 mintute respectively. If both decay folliwing I order, how much time later will concentrations of both of them would be equal?

A substance with initial concentration 'a' follows first order kinetics. In how much time, will the reaction go to completion ?

In a 5 L container,3 moles of A are taken and it immediately starts decomposing with half-life of 10 minutes. After 10min, 3 moles of B are added which undergoes independent decomposition as A with half-life of 5 minutes. If both decompositions follow first order kinetics then how many minutes it will take for the concentration of A and B to become same from the time of start of decomposition of A ?
