For the electrochemical cell M// M^(+) ...

For the electrochemical cell ` M// M^(+) // // X^(-) // X , E^(0) M^(+)// M = 0.44 V and E^(0) (x//x^(-)) = 0.33 V ` . From the one can deduce that

A

`M + X to M^(+) + X^(-)` is the spontaneous reaction

B

`M^(+) + X^(-) to M + X` is the spontaneous reaction

C

`E_("cell")` for this couple = 0.77 V

D

`E_("cell") ` for this couple = -0.11 V

Text Solution

Verified by Experts

The correct Answer is:
B, D
`SRP " of " (M^(oplus) // M ) gt (x //x^(Ɵ)) , " So , " (x^(Ɵ)//x)/(-0.33) "//"(M^(+)//M)/(0.44)`
` E_("cell")^(0) = 0.44 - 0.33 = 0.11 V , x^(Ɵ) + M^(oplus) to x + M ` spontaneous
But `E^(0)` for give cell `=-0.11 V `
