A fuel cell involves combustion of butane at 1 atm and 298 K
`C_(4)H_(10 )(g)13/2 O_(2) (8)rarr 4CO_(2)(g)+5H_(2)0 (l), triangle G^(@)` = -2746 kJ/mol. What is `E^(@)` of a cell?

A

`+4.74 v`

B

`+0.54 v`

C

`+109 v`

D

`+4.37 v`

Text Solution

Verified by Experts

The correct Answer is:
C
In the reaction `C_(4)^(-10)H_(10)^(+10)+13/2O_(2)(g) rarr 4CO_(2)(g)+5H_(2)O(l)`
Chang ein oxidation number of carbon =+16(-10) =+26
`therefore` Number of electrons involved in cell process will be 26
