CHEM102 Study Guide - Final Guide: Chemical Kinetics, Reaction Rate, Reagent

Express reaction rate in terms of Disappearance of reactants Appearance of products Rate law expression Note that these methods of calculating a reaction rate do not represent rate law expressions.

Species is 15) a catalyst? O O_3 HO_2 HO What is the activation energy for the formulation of ozone? 14 kJ 406 kJ 392 kJ none of these the decomposition of dinitrogen pentoxide is described by the chemical equation 2 N_2 O_5 (g) rightarrow 4 NO_2 (g) + O_2 (g) If the rate of disappearance of N_2 O_5 is equal to 1.40 mole/min at a particular moment, what is the rate of appearance of NO_2 at that moment? 1.40 mole/min 5.60 mole/min 2.80 mole/min 0.700 mole/min Which term described the measure of the decrease in the concentration of a product per unit time? reactant energy reaction time reaction rate kinetics the slowest step in a reaction mechanism is called the _____ step. rate-determining elementary rate law termination Which general rate law below corresponds to an elementary bimolecular reaction? Rate - k[A]^2 Rate - k[B] Rate - k[A] [B]^2 Rate - k[A] [B] [C] [D] Which one of the following statements does not describe the equilibrium state? the rate of the forward reaction is equal to the rate of the reverse reaction. the concentration of the reactants and products reach a constant level. the concentration of the reactants is equal to the concentration of the products.

The kinetics of a reaction can only be determined if ___ there is a color change during the reaction The color of the reaction does not change the concentration of a reactant or product can be determined during the reaction. the reaction occurs over a period of years
