Calculate the value of the equilibrium constant (Kc) for the reaction displayed if the following equilibrium concentration data were measured at 1200 K: [Br2(g)] = 0.0001151 mol/L, [Br(g)] = 0.00004423 mol/L.

Question

Br2(g) = 2Br(g)

Answer 1

Kc = (Br)^2/(Br2)
Plug in the concns given and calculate.
