Pt(Cl(2))(p(1))|HCl(0.1M)|(Cl(2))(p(2)),...

`Pt(Cl_(2))(p_(1))|HCl(0.1M)|(Cl_(2))(p_(2)),Pt` cell reaction will be endergonic if

A

`p_(1)=p_(2)`

B

`p_(1)gtp_(2)`

C

`p_(2)gtp_(1)`

D

`p_(1)=1 atm`

Text Solution

Verified by Experts

The correct Answer is:
c
Cell is spontaneous when `p_(2)(` cathode `)gtp_(1)(` anode `)`
At anode `: 2Cl^(c-)(0.1M) rarr Cl_(2)(p_(1))+2e^(-)`
At cathode `: Cl_(2)(p_(2))+2e^(-) rarr 2 C l^(c-)(0.1M)`
`ulbar(Cell reaction : Cl_(2)(p_(2))rarr Cl_(2)(p_(1)))`
`C_(cell)=E^(c-)._(cell)-(0.059)/(2)log.(p_(1))/(p_(2))`
`=0+(0.059)/(2)log `(p_(2))/(p_(1))`
`E_(cell)gt0` if `p_(2)gtp_(1)`.
