In an experiment, 2.00 mol of hydrogen and 3.00 mol of iodine were heated together in a sealed container and allowed to reach equilibrium at a fixed temperature. The container had a fixed volume of 1.00 dm³. At equilibrium, there were 2.40 mol of iodine present in the mixture. H₂(g) + I₂(g) ⇌ 2HI(g) What is the value of the equilibrium constant, K_c?
