Equimolar solutions in the same solvent have

For a spontaneous reaction the ∆G , equilibrium constant (K) and $$E_{cell}^o$$ will be respectively

Aluminium oxide may be electrolysed at 1000^oC to furnish aluminium metal (Atomic mass = 27 amu; 1 Faraday = 96,500 Coulombs). The cathode reaction is Al³⁺ + 3e^- $$\to$$ Al^o To prepare 5.12 kg of aluminium metal by this method would require

The highest electrical conductivity of the following aqueous solutions is of :
