Find the Kc value

Question

Determine the value of Kc for the following reaction if the equilibrium concentrations are as follows: [P4O10]e q = 2.000 moles, [P4]eq = 3.000 moles, [O2]eq = 4.000 M P4O10(s) P4(s) + 5 O2(g)

Answer 1

P₄O₁₀(s) <===>P₄(s) + 5 O₂(g)

Kc = [O₂]⁵ (note: solids are omitted from the equilibrium expression)

Kc = (4.000)⁵

Kc = 1024
