If the $E_{cell}^0$ for a given reaction has a negative value, which of the following gives the correct relationships for the values of ΔG0 and Keq?

ΔG0 < 0; Keq < 1
ΔG0 > 0; Keq < 1
ΔG0 > 0; Keq > 1
ΔG0 < 0; Keq > 1
Explanation:

$E_{cell}^0$ < 0, so it is a non-spontaneous process

ΔG0 = – nFE0 = +ve, so ΔG0 > 0

ΔG0 = – 2.303RT log K

So, K < 1
