`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)`.

Galvanic cells generate electrical energy at the expense of a spontaneous redox reaction. In an electrode concentration cell two like electrodes having different concentrations, either because they are gas electrodes operating at different pressures or because they are amalgams (solutions in mercury) with different concentrations are dipped into the same solution. Eg. An example is a cell composed of two chlorine electrodes with different pressure of Cl_(2) : Pt_(L)|Cl_(2)(P_(L))|HCl(aq)|Cl_(2)(P_(R))|Pt_(R) Where P_(L) and P_(R) are the Cl_(2) pressure at the left and right electrodes. Calculate the EMF of the electrode concentration cell represented by : Hg-Zn(c_(1))|Zn^(+2)(aq)|Hg-Zn(c_(2)) At 25^(@)C.c_(1)=2g of Zn per 100g of Hg and c_(2)=1g of Zn per 50g of Hg
