What is the equilibrium expression for the reaction P 4 s + 5 O 2 g ⇌ P 4 O 1 0 s ?

Options

  1. AK C = P 4 O 10 5 P 4 O 2
  2. BK C = 1 O 2 5
  3. CK C = P 4 O 10 P 4 O 2
  4. DK C = O 2 5

Correct answer

B. K C = 1 O 2 5

Step-by-step solution

In the expression for equilibrium constant species in solid state are not written (i.e, their molar concentrations are taken as 1) P 4 s + 5 O 2 s ⇌ P 4 O 10 s So K C = 1 O 2 5
