Kc relationshipHardQuestion 600434

Question

If K₁ and K₂ are equilibrium constants for A ⇌ B and B ⇌ C respectively, the equilibrium constant for A ⇌ C is:
  1. A
    K₁ + K₂
  2. B
    K₁ × K₂
    Correct
  3. C
    K₁/K₂
  4. D
    √(K₁K₂)

Correct answer

K₁ × K₂

Explanation

When reactions are added, equilibrium constants are multiplied: K(A⇌C) = K₁ × K₂. This follows from the fact that K is expressed as products of concentration terms with stoichiometric exponents.
