Chemistry - Electrochemistry Question with Solution | TestHub

Any redox reaction would occur spontaneously if the free energy change$\left(\mathrm{\Delta }\mathrm{G}\right)$is negative.$\mathrm{\Delta }{\mathrm{G}}^{\mathrm{o}}=\mathrm{}\mathrm{}-\mathrm{n}\mathrm{F}{\mathrm{E}}^{\mathrm{o}}$
Where$\mathrm{n}$is the number of electrons involved,$\mathrm{F}$is the value of Faraday and${\mathrm{E}}^{\mathrm{o}}$is the cell emf.$\mathrm{\Delta }{\mathrm{G}}^{\mathrm{o}}$can be negative if${\mathrm{E}}^{\mathrm{o}}$is positive.
