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.
Which one of the following may represent fraction of number of molecules present after the given interval for gas-I?

A

`t=0 t=100 sec t=200sec`
1 `1/2 1/8`

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.

Show that the gas obeys the approx. equation (PV)/(RT)=[1-((n-1)K_(c))/(V^(n-1))] , where K_(c)=([A_(n)])/([A]^(n)) and V is the volume of the container. Assume that initially one mole of A was taken in the container.
