A solid XY kept in an evacuated sealed container undergoes decomposition to form a mixture of gases X and Y at temperature T . The equilibrium pressure is 10 bar in this vessel. K p for this reaction is?

Options

  1. A25
  2. B100
  3. C10
  4. D5

Correct answer

A. 25

Step-by-step solution

XY ⇌ X ( S ) ( g )         + Y ( g ) P eq = P x + P x = 10 ⇒ P x = 5 K p = P x . ( P y ) = 5 × 5 = 25
