During the working of a galvanic cell and with the passage of time.

Options

A. Spontaneity of the cell reaction decreases, `E_(cell)` decreases
B. Reaction quotient `Q` decreases, `E_(cell)` increases
C. Reaction quotient `Q` increases, `E_(cell)` decreases
D. At equilibrium, `Q=K_(eq),E_(cell)=0`

Answer

a,c,d

Explanation

During the working of a galvanic cell, it reaches equilibrium from its standard conditions.
`implies Quarr` to reach `K_(eq),E_(cell)darr`
Reaction becomes less spontaneous as `E_(cell)darr`.
