Ozone Flashcards
What is the breaking of bonds with light called?
Photodisasociation
What is 1% in ppm?
10000
What is an initiation reaction?
When a radical is formed by another molecule being broken down by light.
What is a propagation reaction?
When a radical reacts with another molecule to produce a radical
What is a termination reaction?
When a radical reacts with another radical to form a non radical
How is ozone produced? Whats the reaction?
O + O ==> O2
O2 + O + UV ==> O3
What is a colourometer?
A device that is used to identify a color change in a reaction. It requies stopping the reaction and taking a sample.
Name 5 things that affect a reactions rate?
- Catalyst
- Temperature
- Form
- Concentration
- Pressure
What is collision theory?
Atoms must collide with a certain energy to react
What is a distrabution curve?
Measures how energy is distrabuted
There is a line on it that indicates the activation energy for a reaction
What is a homogeneos catalyst?
A catalyst that is the same state as what it is catalysing
What is a heterogeneouse catalyst?
A catalyst that is a differnt state from what it is catalysing
What is a catalyst and discrive how it works?
It is a way of reducing the activation enthalpy required for a reaction by offering an alternative reaction pathway that has a lover enthalpy.
3 ways ozone can be removed?
With a hyrolyl: HO + O3 ==> HO2 + O2
HO2 + O ==> HO + O2
With nitrogen monoxide
