The potential of a hydrogen electrode dipped in a solution of pH = 10 is (H₂ is passed at 1 atm)

A cell utilises the reaction Zn (s) + 2H⁺(aq)$\to$Zn²⁺ (aq) + H₂ (g). Addition of H₂SO₄ to the cathode compartment will

\(Z n(s)+C l_{2}(1 a t m) \rightarrow z n^{2+}+2 C l^{-}\)

\(E^{0}_{c e l l}\) of the cell is \(2.12 V .\) To increase \(E_{c e l l}\)

Equilibrium constant of a reaction is related to

For the reaction: \(N_{2} O_{4}(g) \rightleftharpoons 2 N O_{2}(g)\), the vapour density of the mixture at 1 atmospheric pressure is 34.5

The degree of dissociation is:
