`Pt | Cl_2 (P_2) |HCl (0.M) |Pt|Cl_2 (P_2)` , cell reaction will be spontaneous if :

A

` P_1 =P_2`

B

` P_1 gt P_2`

C

` P_2 gt P_1`

D

` P_1 = P_2 =1 ` atm

Text Solution

Verified by Experts

The correct Answer is:
C
`Delta G=- 2.303 RT log K`
for spontaneous `Delta G =- ve`
` - (Delta G)/( 2.303) RT = log P_1/P_2`
`P_2/(((Delta G)/(2. 303 RT))) gt P_1`
` P_2 gt P_1`.
