Chemistry 2080 Spring 2009 Problem Set #3 - due date: Friday February 19th at 2 pm Name:________________ Lab TA Name:__________________ Lab Day/Time:______________________ 1) A commercial process for making nitric acid starts with the platinum-catalyzed oxidation of ammonia (NH 3 ) by oxygen, to form nitric oxide (NO). The unbalanced chemical equation for this reaction is as follows: Pt NH 3 (g) + O 2 (g) –––––––> NO(g) + H 2 O(g) First balance this chemical equation, and then use the data of Table 7.2 in the Petrucci textbook to calculate the standard enthalpy change for the balanced equation.
