1.	0.5 mole of each of H_(2),SO_(2) and CH_(4) are kept in acontainer. A hole was made in the container. After 3 hours, the order of partial pressures in the container will be
Answer» `p_(SO_(2)) gt p_(CH_(4)) gt p_(H_(2))` `p_(H_(2)) gt p_(SO_(2)) gt p_(CH_(4))` `p_(H_(2)) gt p_(SO_(2)) gt p_(CH_(4))` `p_(H_(2)) gt p_(CH_(4)) gt p_(SO_(2))` Solution :Equal MOLES of three gases means equal partial PRESSURES in the beginning. As rate of DIFFUSION `prop sqrt((1)/("Mol mass"))`,therefore, RATES of diffusion will he in the ORDER : `H_(2) gt CH_(4) gt SO_(2)`. Hence, amounts left will be in the order `H_(2) lt CH_(4) lt SO_(2)` or `SO_(2) gt CH_(4) gt H_(2)`. Their partial pressures will also be in the same order.
