Question

The volumes of gases H2, CH4, CO2 and NH3 adsorbed by 1 g of charcoal at 288 K are in the order

Options

A.H2 > CH4 > CO2 > NH3
B.CH4 > CO2 > NH3 > H2
C.CO2 > NH3 > H2 > CH4
D.NH3 > CO2 > CH4 > H2

Solution

Greater the polarity or polarizability, greater will be the extent of adsorption. Hence, H2 < CH4 < CO2 < NH3.
