(b) the equilibriium concentration of ion paris if tghe recombination coefficient for air lions is eaual to `r = 1.67.10^(-8) cm^(3)//s`

The air between two closely separated large plates in a scalted glass tube is uniformly ionised by ultraviolet ragdiation. The air volume between the plates is equal 500cm^(3) , the observed saturation current is equl to 0.48muA . Given that at saturation on an average ions take 1 s in travelling from one plate to another. Find: (a) The equilibrium concentration of ions in saturation state. (b) The production rate of iron pairs if the recombination coefficient for air ions is equal to r=1.67xx10^(-6)cm^(3)//s . Consider that the rate at which ion pairs recombine is given as r N^(2) where N is the ion concentration.

The velocity of air between the collection plates must be
