Electrochemistry

The standard electrode potential $${E^o }$$ and its temperature coefficient $$\left( {{{d{E^o }} \over {dT}}} \right)$$ for a cell are 2V and $$-$$ 5 $$\times$$ 10^$$-$$4 VK^$$-$$1 at 300 K respectively. The cell reaction is Zn(s) + Cu²⁺ (aq) $$\buildrel \, \over \longrightarrow$$ Zn²⁺ (aq) + Cu(s) The standard reaction enthalpy ($$\Delta$$_rH$${^o }$$) at 300 K in kJ mol^–1 is, [Use R = 8 JK^–1 mol^–1 and F = 96,000C mol^–1]
