Question

59. K for the esterification reaction:
CH,COOH + C,H,OH CH,COOC,H+H,O is 4. If 4 mol each of acid and alcohol are taken
initially, what is the equilibrium concentration of the acid:
1)2/3. 2)4/3. 3)3/4. 4)3/2

Answer 1

Explanation: Ans (2)

K = X^2/ ( 4-X)^2 =4

X /( 4-X) = 2

8-2X = X

3X= 8

X = 8/3

CH3COOH] = 4-8/3 = 4/3= 1.33 M
