`Pt(H_(2))(p_(1))|H^(o+)(1M)|(H_(2))(p_(2)),Pt` cell reaction will be exergonic if

A

`P_(1) gt P_(2)`

B

`P_(1) gt P_(2)`

C

`P_(2) gt P_(1)`

D

`P_(1) = 1` atm

Text Solution

Verified by Experts

The correct Answer is:
B
`E_("cell")` for the given change
`E_("cell") = (0.059)/(2) "log" ([H^(+)]xxP_(1(H_(2))))/(P_(2H_(2))xx[H^(+)])`
Thus For `+ve E_("cell") = P_(1H_(2)) gt P_(2H_(2))`
