Two flasks `A` and `B` have equal volume at `100 K` and `200 K` and have `4 atm` and `1 atm` pressures, respectively. The flasks `A` contains `H_(2)` gas and `B` contains `CH_(4)` gas. The collision diameter of `CH_(4)` is twice that of `H_(2)`.   (`i`) Which of the following is true about the mean free path `(lambda)` of the molecules?  (`a`) `lambda` of `H_(2)` is twice that of `CH_(4)`.  (`b`) `lambda` of `CH_(4)` is twice that of `H_(2)`.  (`c`) `lambda` of `H_(2)` is four times that of `CH_(4)`.  (`d`) `lambda` of `CH_(4)` is four times that `H_(2)`.  (`ii`) Which of the following is true about the viscosity of the gases?  (`a`) Viscosity of `H_(2)=2xx` viscosity of `CH_(4)`  (`b`) Viscosity of `H_(2)=3xx` viscosity of `CH_(4)`  (`c`) Viscosity of `H_(2)=` viscosity of `CH_(4)`  (`d`) Viscosity of `H_(2)=(1)/(2)xx` viscosity of `CH_(4)`
