The Speed Of A Reaction Flashcards
1
Q
Rate of a reaction
A
The speed with which the reaction happens in a single unit of time
2
Q
What are ways you can prove a reaction has taken place?
A
- change in temperature
- change in color
- emission of gas
- smell/odor
3
Q
What should you measure to find the rate of a reaction?
A
1) the amount of reactants used up per unit of time
2) the amount of products produced per unit time
4
Q
Factors that affect the rate of a reaction
A
1) surface area
- as the area increases, the rate of the reaction increases
2) temperature
- reaction rate is higher due to increased collision
5
Q
Activation energy?
A
The amount of energy required by the reactants to get converted to products
6
Q
Catalyst?
A
Substances that increase the rate of a reaction by providing an alternate route with low activation energy
