Percentage yield of SO(3) in the followi...

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?

A

`T_(1) gt T_(2) gt T_(3)`

B

`T_(3) gt T_(2) gt T_(1)`

C

`P_(1) lt P_(2) lt P_(3)`

D

`P_(3) lt P_(2) lt P_(1)`

Text Solution

Verified by Experts

The correct Answer is:
A, C
`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)`
