For the following three reactions I, II and III, equilibrium constants are given 1. CO g + H 2 O g ⇌ CO 2 g + H 2 g ; K 1 2. CH 4 g + H 2 O g ⇌ CO g + 3H 2 g ; K 2 3. 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

As equation 3 is obtained on adding equation 1 and equation 2 , so K 3 = K 1 ⋅ K 2 .
