For N H 4 H S ( s ) ⇌ N H 3 ( g ) + H 2 S ( g ) , if K P = 64 a t m 2 , equilibrium pressure of mixture is

Options

  1. A8 atm
  2. B16 atm
  3. C64 atm
  4. D4 atm

Correct answer

B. 16 atm

Step-by-step solution

P N H 3 = P H 2 S So K P = ( P N H 3 ) 2 64 = ( P N H 3 ) 2 P N H 3 = 8 atm Total pressure = P N H 3 + P H 2 S = 8 + 8 = 16 atm
