Question
When galvanic cell started, with passage of time
Options
A.spontaneity of the cell reaction decreases; Ecell decreases
B.reaction quotient Q decreases; Ecell increases
C.reaction quotient Q increases; Ecell decreases
D.at equilibrium Q = Kc; Ecell = 0.
Solution
During the working of cell ECell decreases ᐃG increases, spontaneity decreases at equilibrium
Q = KC, ECell = 0.
Q = KC, ECell = 0.
