Unit 5: Kinetics

Question 1

Zero Order Rate Law

Answer 1

Rate = k

Question 2

First Order Rate Law

Answer 2

Rate = ln[A]t = -kt + ln[A]0

Question 3

Second Order Rate Law

Answer 3

1/[A]t = kt + 1/[A]0

Question 4

Activation Energy (Ea)

Answer 4

Energy needed for a reaction to occur

Question 5

Effective Collisions

Answer 5

Collisions that meet the activation energy

Question 6

Heterogeneous Mixture

Answer 6

A mixture in which all portions are NOT identical

Question 7

Homogeneous Mixture

Answer 7

A mixture in which all portions are identical

Question 8

Elementary Steps

Answer 8

Individual steps that make up a balanced equation

Question 9

Intermediates

Answer 9

Elements that are produced but also fully consumed over the course of the reaction

Question 10

Bimolecular

Answer 10

An elementary step that has two reactants

Question 11

Unimolecular

Answer 11

An elementary step that has one reactant

Question 12

Rate-Determining Step

Answer 12

The slowest step of a reaction

Question 13

Catalyst

Answer 13

Increases the rate by providing an alternative reaction pathway with a lower activation energy of a chemical reaction without being consumed in the process
