The Ozone Story

Question 1

How does pressure affect rate of reaction?

Answer 1

There is greater surface area to volume ratio, therefore moe collisions, therefore more successful collisions per second

Question 2

What does ‘Quantised’ mean?

Answer 2

The amount of energy needed for a molecule to move, rotate, bend or for electrons to change energy level

Question 3

What is a radical?

Answer 3

A species with unpaired electron(s)

Question 4

What happens during Heterolytic bond breaking?

Answer 4

Bond breaks

Question 5

What is the concentration by volume of Nitrogen gas? (%)

Answer 5

78%

Question 6

What is the concentration by volume of Oxygen?

Answer 6

21%

Question 7

What is the concentration by volume of Argon?

Answer 7

1%

Question 8

What is the concentration by volume of Carbon dioxide?

Answer 8

399ppm

Question 9

What are the four types of energy associated with a particle?

Answer 9

Vibrational
Translational
Electronic
Rotational

Question 10

What is the order of energy starting with most energetic to least

Answer 10

Electronic - Vibrational - Rotational - Translational

Question 11

What is photodissociation?

Answer 11

When the molecule absorbs too much radiation that the bonding electrons can no longer bond the atoms together

Question 12

What is produced as a result of photodissociation?

Answer 12

Radicals

Question 13

Why does absorbing infrared radiation make the atmosphere warmer?

Answer 13

Molecules which have absorbed radiation have more kinetic energy which is then transferred to other molecules in the air.

Question 14

Why do some molecules only absorb certain frequencies of radiation?

Answer 14

There are specific frequencies corresponding to the transitions between vibrational energy levels, making the bonds vibrate more

Question 15

What does aqueous bromine test for, if positive what colour change?

Answer 15

C=C go from red/brown to colourless
