Introduction to Electrochemistry

Define electrochemistry.

Define electrochemistry.

Consider two reactions

 $\mathrm{X}⟶\mathrm{Y}, \mathrm{\Delta G}°=-386\frac{\mathrm{kJ}}{\mathrm{mol}}$

${\mathrm{M}}^{2+}⟶{\mathrm{M}}^{4+}+2{\mathrm{e}}^{-},\mathrm{E}°=-\mathrm{pV}$

It is given that all the energy released from the conversion of $\mathrm{X}$ to $\mathrm{Y}$ is used in the oxidation of ${\mathrm{M}}^{2+}$ to ${\mathrm{M}}^{4+}$. Under standard conditions, on conversion of 1 mole of $\mathrm{X}, 4$ moles of ${\mathrm{M}}^{2+}$ are oxidised. The value of $100\mathrm{p}$ is (use $\mathrm{F}=96500{\mathrm{Cmol}}^{-1}$ )
