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.
(ii) THe rate at which initially molecules will come out in gas I as comapred to gas II will be greater in gas II if initial number of molecules are same.
(iii) The time required for moles to get reduced from 1 to `0.8` in gas I and 2 to `1.6` in gas II will be same.
(iv) for the two gases, moles remaining in the container after some ubterval should be in Geometrical Progression.
