Question

Which of the following does not represent Kbiphasic?

(a) \(\frac{[B_{org}]}{[A_{org}]}\)

(b) \(\frac{[B_t]}{[A_t]}\)

(c) \(K_w (\frac{1+αP_B}{1+αP_A})\)

(d) \(K_w \frac{P_B}{P_A}\)

I had been asked this question in an online interview.

Answer 1

Correct answer is (a) \(\frac{[B_{org}]}{[A_{org}]}\)

Best explanation: Kbiphasic is the apparent equilibrium constant and is represented in the following ways:

\(K_{biphasic} = \frac{[B_t]}{[A_t]}\)

\(K_{biphasic} = K_w (\frac{1+αP_B}{1+αP_A})\)

\(K_{biphasic} = K_w \frac{P_B}{P_A}\)

Equilibrium constant for organic solvent reaction is given by Korg = \(\frac{[B_{org}]}{[A_{org}]}\),

Where Aorg and Borg gives the concentration of A and B in organic solvents respectively.
