Question
Given is a concentrated solution of a weak electrolyte $A_x B_y$ of concentration ' $c$ ' and dissociation constant ' $K$ '. The degree of dissociation is given by :
Select the correct option:
A
$\left[\mathrm{K} \times \mathrm{c}^{x+y-1} x^x y^y\right]^{x+y}$
B
$\left(\frac{\mathrm{K}}{\mathrm{c}^{x+y-1} x^x y^y}\right)^{\frac{1}{x+y}}$
C
$\left(\frac{\mathrm{c}^{x+y-1} x^x y^y}{\mathrm{~K}}\right)^{x+y}$
D
$\left(\frac{c^{x+y-1} x^x y^y}{\mathrm{~K}}\right)^{\frac{1}{x+y}}$
✓ Correct! Well done.
