Review: Do Now
Explain why each answer is partially correct. Then, why one of the choices is MOST CORRECT. H2 (g) + Cl2 (g)  2HCl (g) Kp = 2 x 1030 at 298 K HCl (g) can be synthesized from H2 (g) and Cl2 (g) as represented above. A student studying the kinetics of the reaction proposes the following mechanism. Step 1: Cl2 (g)  2 Cl (g) (slow) ΔHo = 242 kJ/molrxn Step 2: H2 (g) + Cl (g)  HCl (g) + H (g) (fast) ΔHo = 4 kJ/molrxn Step 3: H (g) + Cl (g)  HCl (g) (fast) ΔHo = -432 kJ/molrxn Which of the following statements identifies the greatest single reason that the value of Kp for the overall reaction at 298 K has such a large magnitude?
