The increasing order of effusion among the gases `H_(2), O_(2), NH_(3)` and `CO_(2)` is

Options

A. `COgtO_(2)gtCO_(2)gtC_(2)H_(2)`
B. `O_(2)gtCO_(2)gtCOgtC_(2)H_(2)`
C. `C_(2)H_(2)gtCO_(2)gtO_(2)gtCO`
D. `O_(2)gtCO_(2)gtC_(2)H_(2)gtCO`

Answer

C

Explanation

Greater the Henry’s constant `(K_(H))`, lower is the solubility at the same pressure.
`therefore` Order of `K_(H):COgtO_(2)gtCO_(2)gtC_(2)H_(2)`
`therefore` Order of solubility : `C_(2)H_(2)gtCO_(2)gtO_(2)gtCO`.
