Rates of Reaction

HideShow resource information
How can rate be measured?
Amount of reactant used or product produced in a given time
1 of 7
What is collision thoery?
Particles must 1) collide and 2) have enough energy to react
2 of 7
What is activation energy
Minimum amount of energy needed for a reaction to happen
3 of 7
Name 3 things that can change the rate of a reaction
Temperature, Surface area, Concentration, Catalyst
4 of 7
What happens to the rate of reaction if the concentration of a solution is doubled?
Rate doubles
5 of 7
What is a catalyst?
Catalyst changes the rate of reaction but is itself unchanged at the end of the reaction.
6 of 7
Why does increasing the surface area increase the rate of a reaction?
Larger surface area means there are more particles available for collision so collisions happen more often and more of them are successful
