You are given the following group of particles `n_(1)` represents the number of molecules with speed `upsilone_(1)`

Your are given the following group of particles, n_(i) represents the number of molecules with speed v_(i) (P_(2))/(P_(1))=(m_(2))/(m_(1)) : (p_(2))/(76)=(m_(1)+(50)/(100)m_(1))/(m_(1))=(3)/(2) calculate (i) average speed (ii) rms speed (iii) most probable speed.

1 mole by definition represents same number of particles as

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?
