Q21 / 120 · VITEEE 2006 · Chemistry

For a cell reaction to be spontaneous, the standard free energy change of the reaction must be

A
zero
B
positive
C
infinite
Correct answer
D
negative

Solution

For spontaneous reaction free energy change is negative. $\Delta \mathrm{G}=-\mathrm{nFE}$

Hence, the correct answer is option: 'D'.
