On the basis of H-bonding explain that the second ionization constant `K_2` for fumaric acid is greater than for maleic acid.

Explain : Acidity of maleic acid is greater than fumaric acid.

Why the ionization potential of M^(2+) is not very much greater than M^(+) ?

Explain why 2 - fluorobutanoic acid is more acidic than 2 - chlorobutanoic acid.

On the basis of lanthanoid contraction, explain the following : Treands in acidic character of lanthanoid oxides.

HF is weaker acid than HI. Explain.

2-chloroethanoic acid is a stronger acid than ethanoic acid . Why ?

At a given temperature, for the reaction AhArrB , the rate constant (k_(f)) of the forward reaction is greater than that of the backward reaction (k_(b)) . Is the value of equilibrium constant (K) for this reaction greater than, less than or equal to 1?

The first ionisation energy of the Be is greater than that of B but the second ionisation energy of Be is less than that of B. explain.

The concentration of a weak monobasic acid is 0.2(M). If the acid is 2% ionised in the solution, then find the pH of the solution and ionisation constant of the acid.

Perchloric acid is a stronger acid than sulphuric acid. Explain.
