For the following three reactions a, b and c , equilibrium constants are given: a. CO ( g )+ H ₂ O ( g ) CO ₂( ~g )+ H ₂( ~g ) ; K ₁ b. CH ₄( ~g )+ H ₂ O ( g ) CO ( g )+3 H ₂( ~g ) ; K ₂ c. CH ₄( ~g )+2 H ₂ O ( g ) CO ₂( ~g )+4 H ₂( ~g ) ; K ₃ Which of the following relations is correct?

Options

  1. AK ₁ K ₂ = K ₃
  2. BK ₂ ~K ₃= K ₁
  3. CK ₃= K ₁ ~K ₂
  4. DK ₃ K ₂^3= K ₁^2

Correct answer

C. K ₃= K ₁ ~K ₂

Step-by-step solution

Equation (c) = equation (a) + equation (b) Thus K ₃= K ₁ K ₂
