Chemistry - Chemical Equilibrium Question with Solution | TestHub

$\mathrm{C}{\mathrm{u}}^{2+}+2\mathrm{F}{\mathrm{e}}^{2+}\rightleftharpoons \mathrm{C}\mathrm{u}+2\mathrm{F}{\mathrm{e}}^{3+}$
For this reaction at equilibrium the concentration of$\mathrm{C}{\mathrm{u}}^{2+}$ions is not changed by the addition of Cu as it is solid. So its molar concentration is always taken as unity.
