Question 1
Reaction A+B⇋ C+D is a reversible reaction which means if we start with A + B we get C + D and if we start with C + D we get A + B.
Given that when A+B→ C+D, Δ G = - ve, when we start with A and B.
What will be Δ G for the reaction C+D → A+B if we start with C and D.
Question 2
Statement-1: Oxidation potential for (Pt) H2/NH4OH(1M) electrode is greater than
(Pt) H2/CH3COOH (1M) electrode.
Statement-2: Higher is the [H+] in anode compartment greater is oxidation potential
for corresponding hydrogen electrode.
Question 3
The concentration of Cd2+ in a solution in equilibrium with a precipitate of cadmium sulphide is found to be 4 times greater than the molar concentration of the S2-. Find out the concentration of Cd+2 Ksp of CdS is 6 .4 × 10-27.
Question 4
The reaction is Fe2+ + Ag+⇋ Fe3+ + Ag. The equilibrium constant at 25oC for the reaction (Given: =0.799 volt and =0.771volt) is
