`Pt|Cl_(2)(P_(1)atm)|HCl(0.1M)|Cl_(2)(P_(2)atm)|Pt`, cell reaction will be spontaneous if

A

`p_(1)=p_(2)`

B

`p_(1)gtp_(2)`

C

`p_(2)gtp_(1)`

D

`P_(1)=P_(2)=1atm`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_(cell)=E_(cell)^(0)-(0.591)/(2)log_(10)((P_(Cl_(2)_(anode)))/(P_(Cl_(2)(cathode))))=0-(0.0591)/(2)log_(10)((P_(1))/(P_(2)))`
if `P_(1)ltP_(2),E_(cell)=+ve` (spontaneous)
