Taylor and Crist [Journal of the American Chemical Society, 63, 1381 (1941)] studied the reaction between hydrogen and iodine to form hydrogen iodide.
They obtained the following data for the concentrations of H2, I2 and HI at equilibrium in units of moles per liter. Calculate the value of Kc for each run.
Trial [H2] [I2] [HI] KcI 0.0032583 0.0012949 0.015869II 0.0046981 0.0007014 0.013997III 0.0007106 0.0007106 0.005468
Realizing that there will be deviation due to experimental error, is Kc constant for this reaction? Yes
