At 445°C, Kc for the following reaction is 0.020. 2HI(g) - H2(g) + I2(g) A mixture of H2 2, and HI in a vessel at 445°C has the following concentrations: [HI] =0.90 M, [H2] = 0.50 M and [l,] = 0.25 M. Which one of the following statements, is TRUE for this system? O Qc = Kc; the system is at equilibrium. O Qc is less than Kc; more hydrogen and iodine will be produced. Qc is less than Kc; more HI will be produced. O Qc is greater than Kc; more hydrogen and iodine will be produced. O Qc is greater than Kc; more HI will be produced.
