For the reaction A B ( g ) ⇌ A ( g ) + B ( g ) AB is 33% dissociated at a total pressure of P. Therefore, P is related to K p by one of the following options.

Options

  1. AP = 3 K p
  2. Bp = K p
  3. CP = 8 K p
  4. DP = 4 K p

Correct answer

C. P = 8 K p

Step-by-step solution

p A = 0.33 1.33 P , p B = 0.33 1.33 P p A B = 0.67 1.33 P K P = p A × p B p A B K P = 0.33 × 0.33 × P 0.67 × 1.33 P K p = 8 P = 8 K P .
