What is the equilibrium constant expression for the reaction P 4 ( s ) + 5 O 2 ( g ) ⇌ P 4 O 10 ( s )

Options

  1. AK c [ P 4 O 10 ] [ P 4 ] [ O 2 ] 5
  2. BK c = 1 [ O 2 ] 5
  3. CK c = [ O 2 ] 5
  4. DK c = P 4 O 10 5 P 4 O 2

Correct answer

B. K c = 1 [ O 2 ] 5

Step-by-step solution

As both P 4 and P 4 O 10 are solid so they are neglected. K C = 1 ( O 2 ) 5
