Which of the following statements about the spontaneous reaction occuring in a galvanic cell is al-

ways true ?

A) E e > 0,4Gº <0, and Q<K 【❌】

B) Ec>0,4Gº <0, and Q>K【❌】

C) Ece > 0, AG° > 0, and Q>K【❌】

D) E > 0, 4Gº <0, and Q<K【✔️】

$\huge\bold\star\underline\mathbb\orange{explaination}$

For a reaction to be spontaneous we have to know that always ΔG0<0 always.

We know for a galvanic cell,

ΔG=−nFEcell0

So for ΔG0<0 then  Ecell0>0.

We know that reaction will be spontaneous Q<K

And hence option D is correct answer.
