2) Potential Energy Diagrams Homework A) Rewrite the following reactions from Reference Table I, placing the energy on the appropriate side: Reaction N 2 (g) + 3 H 2 (g) 2 NH 3 (g) Rewritten with Energy on the Correct Side N 2 (g) + 2 O 2 (g) 2 NO 2 (g) H 2 (g) + I 2 (g) 2 HI (g) B) For the same reactions above, indicate if they are endothermic or exothermic and also indicate whether the products are stable or unstable. Reaction N 2 (g) + 3 H 2 (g) 2 NH 3 (g) Exothermic or Endothermic? Stable or Unstable Products? N 2 (g) + 2 O 2 (g) 2 NO 2 (g) H 2 (g) + I 2 (g) 2 HI (g) C) For the following blank PE Diagram, sketch the shape of an endothermic curve and label: You do not have to put any numbers in. H reactants , H products , H activated complex , activation energy and ∆H. © 2009, Mark Rosengarten AE 24
