NEET Chemistry Ionic Equilibrium MCQ Question

Type: MCQ-fact-Medium-Class 11

What is the equilibrium constant expression for the dissociation of acetic acid (HAc) in water?

A

K_a = [H^+][Ac^-]/[HAc]

B

K_a = [HAc]/[H^+][Ac^-]

C

K_a = [Ac^-]/[H^+][HAc]

D

K_a = [H^+][HAc]/[Ac^-]

Correct Answer

Option A

Detailed Explanation

The equilibrium constant expression for the dissociation of acetic acid is given by K_a = [H^+][Ac^-]/[HAc], which reflects the concentrations of the products and reactants at equilibrium.
