Flashcards in Chapter 16 Deck (17):
1

Stated as the change in concentration of a reactant or product per unit time

Reaction rate

2

States that Atoms must Collide to react

Collision theory

3

A temporary unstable arrangement of atoms in which old bonds are breaking in new bonds are forming

Activated complex

4

Minimum amount of energy particles must have to form the activated complex and lead to a reaction

Activation energy

5

Substance that increases the rate of a chemical reaction without being consumed in the reaction

Catalyst

6

A substance that slows down reaction rates

Inhibitor

7

Exists in a physical state different than that of the reaction it catalyzes

Heterogeneous catalyst

8

Exists in the same physical state as the reaction it catalyzes

Homogeneous catalyst

9

Expresses the relationship between the rate of a chemical reaction and the concentration of reactants

Rate law

10

A numerical value that relates the reaction rate in the concentrations of reactants at a given temperature

Specific rate constant

11

For a reactant defines how is the rate is affected by the concentration of that reactant

Reaction order

12

Determines reaction order by comparing the initial rates of a reaction carried out with varying reactant concentration

Message of initial rates

13

Slope of the straight line tangent to the curve at a specific time

Instantaneous rate

14

One that consists of two or more elementary steps

Complex reaction

15

Complete sequence of elementary steps that make up a complex reaction

Reaction mechanism

16

Substance produced in one elementary step and consumed in a subsequent elementary step

Intermediate

17

Slowest elementary step in your complex reaction

Rate determining step
