Question

For a spontaneous reaction, the ΔG, equilibrium constant (K) and `"E"_"cell"^circ` will be respectively.

पर्याय

• - ve, > 1, - ve

• - ve, < 1, - ve

• + ve, > 1, - ve

• - ve, > 1, + ve

Answer 1

- ve, > 1, + ve

Explanation:

For spontaneous reaction, AG should be negative.

Equilibrium constant should be more than one.

ΔG = - 2.303 RT log K_c, If K_c = 1 then

ΔG = 0; If K_c > 1 then ΔG = - ve.

Again, ΔG = - nFE°_cell.

E°_cell must be + ve to have ΔG -ve.
