Which one of the following is the correct quadratic form of the Ostwald's dilution law equation

Options

A. `alpha^(2)+alphaK -K = 0`
B. `alpha^(2)C-alphaK -K =0`
C. `alpha^(2)C-alphaK+K = 0`
D. `alpha^(2) C+alphaK +K=0`

Answer

A

Explanation

According to Ostwald.s dilution law
`K = (Calpha^(2))/(1-alpha)`
or `K - Kalpha = Calpha^(2)`
or `Calpha^(2) + Kalpha - K = 0 `
