Question

What is the correct equilibrium constant expression for equation P2(g)

2 F20(g) = 2 PO(g) + 2 F2(g) ?

Answer 1

k = [F2]² [PO]² / [P2] [F2O]²

Step-by-step explanation:

In a chemical equilibrium, the equilibrium constant expression is written as the ratio between the molar concentration of the products over the molar concentration of the reactants. Each species powered to its reaction coefficient. For the equilibrium:

P2(g) + 2F2O(g) ⇄ 2PO(g) + 2F2(g)

The equilibrium constant, k, is:

k = [F2]² [PO]² / [P2] [F2O]²
