Topic 6.1 - collision theory and rates of reaction

Question 1

Instantaneous rate

Answer 1

The rate at a specific point in the reaction

Question 2

Initial rate

Answer 2

The rate at the beginning of the equation

Often used to compare rate of reaction

Question 3

Average rate

Answer 3

Rate of the reaction over time

Question 4

Homogenous catalyst

Answer 4

In the physical same state as the reactants

Question 5

Heterogenous catalyst

Answer 5

In the opposite physical state as the reactants

Question 6

Ineffective collision

Answer 6

Orientation of the reaction is not favourable so the collision does not cause a reaction to occur

Question 7

Effective collision

Answer 7

Orientation of the reaction is favourable so the collision does cause a reaction to occur

Question 8

Maxwell-Boltzmann energy curve

Answer 8

x-axis: Kinetic energy
y-axis: Fraction of particles with kinetic energy

(Look at page 170 for what it should look like)

Question 9

Temperature on a Maxwell-Boltzmann energy curve

Answer 9

Broader curve
