Percentage yield of SO_(3) in the following reaction is plotted against pressure at definite temperatures. 2SO_(2(g)) +O_(2(g)) harr 2SO_(3(g)), Which of the following relation is correct?

Answer»

`T_(1) GT T_(2) gt T_(3)`
`T_(3) gt T_(2) gt T_(1)`
`P_(1) lt P_(2) lt P_(3)`
`P_(3) lt P_(2) lt P_(1)`

Solution :`SO_(2)+O_(2) HARR 2SO_(3)` is exothermic
`:.` as `T UARR`, % yield `darr`
`:. T_(1) gt T_(2) gt T_(3)`
and as `P uarr`, % yield `uarr`
`:. P_(3) gt P_(2) gt P_(1)`
