Question
Pt | (H2) | pH = 1 || pH = 2 | (H2)Pt
1 atm 1 atm
The cell reaction for the given cell is :
1 atm 1 atm
The cell reaction for the given cell is :
Options
A.spontaneous
B.non - spontaneous
C.equilibrium
D.none of these
Solution
H2 → 2H+(10-2M) + 2e-
2H+(10-3 M) + 2e- → H2
2H+(10-3M) → 2H+(10-2M)
E = 0 -
log 
E → - ve (Non spontaneaous).
2H+(10-3 M) + 2e- → H2
2H+(10-3M) → 2H+(10-2M)
E = 0 -
log E → - ve (Non spontaneaous).
