Rate Of Reaction Flashcards
1
Q
What’s an example of a really fast reaction?
A
An explosion
2
Q
What are the four things which affect the rate of reaction?
A
- temperature
- concentration
- catalyst
- surface area of solids
3
Q
What is the equation for finding out the rate of reaction?
A
Rate of reaction = amount of product formed/time
4
Q
How do you measure the rate of reaction by precipitation?
A
- observe a mark through the solution and measure how long it takes to disappear
- the quicker the mark disappears, the quicker the reaction
- the result can be subjective as different people will stop seeing it at different points
5
Q
How do you measure the rate of reaction by measuring the change in mass?
A
- as gas disappears the mass lost can be easily measured using a balance
- the quicker the mass falls, the faster the reaction
- the most accurate of methods
6
Q
How do you measure the rate of reaction by messing the volume of gas given off?
A
- the more gas given off during a given time, the faster the reaction
- the gas given off by the reaction can be read using the markings on the syringe
7
Q
What is an example of a slow reaction?
A
Rusting iron
