1.1 Rate Of Reaction Flashcards
What are the 4 variables when it comes to the rate of a reaction?
- temperature
- concentration
- use of catalyst
- particle size
When the temperature of a reaction is increased….
The rate of reaction is faster.
When the concentration of a reaction is higher…
The rate of reaction speeds up.
When there’s a decreased particle size…
The rate of reaction speeds up.
When a catalyst is used during a reaction…
The rate of reaction speeds up.
Average rate of reaction=
Change in measurable quantity OVER change in time.
‘Measurable quantity’….
Is the concentration, mass or volume of a reactant or product.
When the concentration of a reaction is lower….
Slower rate of reaction.
When there is no catalyst present…
Slower rate of reaction.
When the temperature is lower…
Slower rate of reaction.
When there’s a bigger particle size…
The rate of reaction is slower.
