The standard electrode potential

\left(\mathrm{E}^0\right)

of the Daniel cell is 1.1 V and the overall cell reaction can be represented as

\mathrm{Zn}(\mathrm{s})+\mathrm{Cu}^{2+}(\mathrm{aq}) \rightarrow \mathrm{Zn}^{2+}(\mathrm{aq})+\mathrm{Cu}(\mathrm{s})

. Under which of the following conditions will the cell potential be higher than 1.1 V ?

Options

A $1.0 \mathrm{M} \mathrm{Zn}^{2+}, 1.0 \mathrm{M} \mathrm{Cu}^{2+}$
B $1.2 \mathrm{M} \mathrm{Zn}^{2+}, 1.2 \mathrm{M} \mathrm{Cu}^{2+}$
C $0.1 \mathrm{M} \mathrm{Zn}^{2+}, 1.0 \mathrm{M} \mathrm{Cu}^{2+}$
D $1.0 \mathrm{M} \mathrm{Zn}^{2+}, 0.01 \mathrm{M} \mathrm{Cu}^{2+}$

Correct answer

C. $0.1 \mathrm{M} \mathrm{Zn}^{2+}, 1.0 \mathrm{M} \mathrm{Cu}^{2+}$
