Rates of Reaction

What 2 way can be used to find the rate of a chemical reaction?
Amount of reactant used/time or Amount of product formed/time
1 of 7
What is the activation energy?
The minimum amount of energy particles must have to react.
2 of 7
Increasing the temperature causes what in a chemical reaction?
It increases the speed of the reacting particles so that they collide more frequently and more energetically. This increases the rate of reaction.
3 of 7
Increasing the pressure of reacting gases causes what in a chemical reaction?
It increases the frequency of collisions and so increases the rate of reaction.
4 of 7
Increasing the concentration of reactants in solutions causes what in a chemical reaction?
It increases the frequency of collisions and so increases the rate of reaction.
5 of 7
Increasing the surface area of solid reactants causes what in a chemical reaction?
It increases the frequency of collisions and so increases the rate of reaction.
6 of 7
What do catalysts do?
They change the rate of chemical reactions but are not used up during the reaction.
