Kinetics

Question 1

Collision theory

Answer 1

Explain how chemical reactions occur and why reaction rates differ.

Reactions happen when particles collide with enough energy and proper orientation

Question 2

Maxwell-Boltzmann distribution

Answer 2

Describes the spread of energies of particles in a gas showing that most particles have moderate energy with fewer having very low or very high energies

Question 3

Effect of temperature on Maxwell-Boltzmann distribution

Answer 3

Increasing temperature makes curve flatter and broader.

Shifting the peak to higher energy and increasing the number of particles with enough energy to react

Question 4

Effect of concentration on Maxwell-Boltzmann distribution

Answer 4

No change to the shape

Question 5

Effect of pressure on Maxwell-Boltzmann distribution

Answer 5

Does not change the shape

Question 6

Effect of a catalyst on Maxwell-Boltzmann distribution

Answer 6

Increases the rate of reaction by finding an alternative path

Shape of graph is not changed
