The standard free energy change free energy for the following reaction is -210 KJ. What is the standard cell potential ?
`2H_(2)O_(2)(aq)rarr2H_(2)O(l)+O_(2)(g)`

A

`+0.752`

B

`+1.09`

C

`+0.420`

D

`+0.640`

Text Solution

Verified by Experts

The correct Answer is:
B
n=2 for given reaction so `DeltaG^(@)=-nFE_("cell")^(@)`
`-210xx1000=-2xx96500xxE_("cell")^(@)`
`-E_("cell")^(@)=1.09V`
