sf(DeltaG^@=+147color(white)(x)kJ)

Explanation:

sf(DeltaG^@=-nFE^@)

:.sf(DeltaG^@=-2xx9.65xx10^(4)xx-0.76=+147color(white)(x)kJ)

The +ve value means that the reaction cannot take place under standard conditions as it has been written.

The spontaneous reaction is:

sf(Zn_((s))+2H_3O_((aq))^(+)rarrZn_((aq))^(2+)+H_(2(g))+2H_2O_((l)))

For which sf(DeltaG^@=-147color(white)(x)kJ)
