For the galvanic cell \(\text{Zn}| \text{Zn}^{2+}(0.10\ \text{M}) || \text{Cu}^{2+}(0.010\ \text{M})| \text{Cu}\) the standard reduction potentials are \(E^{\circ}_{\text{Cu}^{2+}/\text{Cu}} = +0.34\) V and \(E^{\circ}_{\text{Zn}^{2+}/\text{Zn}} = -0.76\) V. Calculate the cell potential at 298 K using the Nernst equation and state whether the cell reaction is spontaneous under the given conditions.
