Under a given condition, it is found that two separate gases effuse out of two separate containers in such a way that they follow the equation (dN)/(dt)=-K_(1)N and (dN)/(dt)=-K_(2)N K_(1)=6.93xx10^(-2) sec^(-1). K_(2)=6.93xx10^(-5) sec where N is no of molecule remaining in the container. Identify the correct option regarding sequence of (True) and (False) statements (i) The time required for moles of gas I to get reduced to half of original and that of gas II to be reduced to half of original is independent of initial moles of gas I and gas II.
