Practice Problems: Reaction Rates and Rate Laws (13.1-13.3) 1. Consider the reaction N 2 (g) + 3H 2 (g) 2 NH 3 (g) and complete the following statements: The rate of disappearance of N 2  is ____ times the rate of disappearance  of H 2 .  The rate of formation of NH 3  is ____ times the rate of disappearance of H 2 The rate of formation of NH 3  is ____ times the rate of disappearance of N 2 . 2.  The rate of formation of dichromate ions is 0.14 mol ٠ L -1 ٠ s -1  in the reaction  2 CrO 4 2- (aq) + 2H + (aq)   Cr 2 O 7 2- (aq) + H 2 O(l).  What is the rate of reaction of  chromate ions in the reaction?  What is the unique rate of the reaction? 3.  Nitrogen dioxide decomposes at 6.5 x 10 -3  mol ٠ L -1 ٠ s -1  by the reaction 2 NO 2 (g)   2  NO(g) + O 2 (g).  (a) Determine the rate of formation of O 2 .  (b) What is the unique  rate of the reaction? 4.  Express the units for rate constants when the concentrations are in moles per liter and
