Question

The cell reaction for the given cell is spontaneoous if:
`Pt_(Cl_(2))|Cl^(-)(1M)||Cl^(-)(1M)|Pt_(Cl_(2))`
A. `P_(1) gt P_(2)`
B. `P_(1) lt P_(2)`
C. `P_(1) = P_(2)`
D. `P_(2) = 1` atm

Answer 1

Correct Answer - b
`E_(cell) = E_(OP_(CI))^(@) +E_(RP_(CI))^(@) + (0.059)/(2) log`
`([CI^(-)]_(LHS)^(2)P_(2))/([CI^(-)]_(RHS)^(2)P_(1)) = (0.059)/(2)log.(P_(2))/(P_(1))`
`E_(cell)` is `+ve` when `P_(2) gt P_(1)`
