rates of reaction Flashcards
1
Q
what are rates of reaction
A
the speed at which the products are formed from the reactants in a chemical reaction
2
Q
factors that effect rates of reaction
A
- temperature
- concentration
- pressure
- catalyst
- surface area
3
Q
how does increasing surface area increase of rates of reaction
A
increasing surface area reactants increases the chance of collisions leading to a faster reaction
4
Q
rate of reaction calculation
A
change in amount of a reactant or a product / time
5
Q
how to measure rate/speed of a reaction
A
measure the time it takes for the reaction to finish
