Which of the following expressions correctly represents the equivalent conductance at infinite diluation of Al₂(SO₄)₃. Given that $$\mathop \Lambda \limits^ \circ $$_Al³⁺ and $$\mathop \Lambda \limits^ \circ $$_{so$$_4^{2 - }$$} are the equivalent conductances at infinite dilution of the respective ions?

An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to

For the reduction of silver ions with copper metal, the standard cell potential was found to be + 0.46 V at 25^oC. The value of standard Gibb's energy, $$\Delta $$G^o will be
(F = 96500 C mol^$$-$$1)

Given :
(i)   Cu²⁺ + 2e^$$-$$ $$ \to $$ Cu,  E^o = 0.337 V
(ii)  Cu²⁺ + e^$$-$$ $$ \to $$ Cu⁺,  E^o = 0.153 V
Electrode potential, E^o for the reaction,
Cu⁺ + e^$$-$$ $$ \to $$ Cu,  will be
