Question

For a chemical reaction if the free energy change is negative. then $E_{cell}$ will be

• A. $>0$
• B. $<0$
• C. $=0$

Answer 1

The correct option is A $>0$

$\Delta G_{\mathrm{cell}}=-{\mathrm{nFE}}_{\mathrm{cell}}\mathrm{then}\Delta G_{\mathrm{cell}}<0-\mathrm{ve}=-{\mathrm{nFE}}_{\mathrm{cell}}{E}_{\mathrm{cell}}>0$
