Practice Questions for Reaction Rates–2 An AP Chemistry In-Class Activity 1) Write an expression for the rate of reaction in terms of a changing concentration for each of the following reactions: a) C 4 H 8 (g) 2C 2 H 4(g) b) H 2(g) + I 2(g) 2HI (g) c) 2NO 2(g) + O 3(g) N 2 O 5(g) + O 2(g) 2) Nitrogen monoxide reacts with chlorine to form nitrosyl chloride. NO (g) + 1/2Cl 2(g) NOCl (g) The figure shows the increase in nitrosyl chloride concentration under appropriate conditions. (The concentration of nitrosyl chloride starts at 0 although this fact is difficult to see in the graph). a) Write an expression for the rate of reaction in terms of a changing concentration. b) Calculate the average rate of reaction between 40 and 120 sec. c) Calculate the instantaneous rate of reaction after 80 sec. 3) The equation for a reaction is: 4NO 2(g) + 2 H 2 O (g) + O 2(g) 4 HNO 3(g) Which one of the following is not numerically equal to the others? (Explain why). a)
