For the following concentration cell, to be spontancous `Pt(H_2)P_1` atm. `|HCl |Pt(H_2) P_2 ` atm which of the following is correct ?

Options

A. `P_1 = P_2 `
B. `P_1 lt P_2 `
C. `P_1 gt P_2 `
D. can't be predicted.

Answer

C

Explanation

Pt `(H_(2)) P_(1)` atm `|P(H_2)P_2` atm for spontaneous reaction. `E_eth` should be positive so `P_1 gt p_2`
`E_("cell")=0.059/2 log (p_1)/(P_2)`
Also if ` p_1gt p_2 ` oxidation of R.H.S electrode.
