Question

Express the equilibrium constant for the combustion of propane in the balanced chemical equation c3h8(g)+5o2(g)???3co2(g)+4h2o(g)

Answer 1

combustion reaction

Step-by-step explanation:

there is oxides in the equation c3h8(g)+5o2(g)3co2(g)+4h2o(g)

Answer 2

according to the balanced equation:
C3H8(g) + 5O2(g) ↔ 3CO2(g) + 4 H2O (g)
aA + bB ↔ cC + dD

according to K formula when:
K = concentration of the products / concentration of the reactants

K = [C]^c[D]^d / [A]^a[B]^b
when [A],[B],[C]and[D] is the concentrations
and a,b,c and d is the no of moles
∴ K = [CO2]^3[H2O]^4 / [C3H8] [ O2]^5
