Flashcards in Ch 5: Chemical Kinetics Deck (12):
1

increasing the ____ will increase reaction rate (except for zero-order reactions) because there are more effective collisions per time

concentration of reaction

2

increasing the temperature will ____ the reaction rate because the particles kinetic energy is increased

increased

3

changing the medium can increase or decrease reaction rate depending on

how the reactants interact with the medium

4

adding a catalyst ____ reaction rate because

increases

lowers activation energy

5

rate orders

usually do not match stoichiometric coefficents

6

rate laws must be determined by

experimental data

7

rate order is

sum of all individual rate orders in the rate law

8

zero-order reactions have _______
can only be affected by ____
conc vs time curve is _____ with a slope of ___

constant rate that does not depend on the concentration of reactant

temperature or a catalyst

straight line ; -k

9

conc vs. time is ___
slope of a ____ is -k

nonconstant rate that depends on the concentration of the reactant

nonlinear

ln [A] vs time plot

10

nonlinear

1/ [A] vs time plot

11
