Question
Pt 
(where p1 and p2 are pressures) cell reaction will be spontaneous if :
(where p1 and p2 are pressures) cell reaction will be spontaneous if :Options
A.p1 = p2
B.p1 > p2
C.p2 > p1
D.p1 = 1 atm
Solution
H2(P1) → 2H+ + 2e-
2H+ + 2e- → H2(P2)
H2(P2) → H2(P2)
E = 0 -
log 
P2 < P1 for E → +ve
2H+ + 2e- → H2(P2)
H2(P2) → H2(P2)
E = 0 -
log P2 < P1 for E → +ve
