January 2, 2018 Do Now (6 min) Learning target: I CAN Identify oxidation numbers and define oxidation and reduction Do Now (On your DO NOW MC Sheet): Answer the first one only. Complete the Table. Learning Target: I CAN Identify oxidation numbers and define oxidation and reduction

January 2, 2018 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?

Review: Do Now January 2, 2018 Options Why is each option partially right? Choose the most correct answer, and why The activation energy for step 1 of the mechanism is large and positive.   The activation energy for step 2 of the mechanism is small and positive. The value of ΔSo for the overall reaction is small and positive. The value of ΔHo for the overall reaction is large and negative.
