Rates of Reaction

HideShow resource information
What happens if two particles collide but they do not have enough activation energy?
DO NOT REACT (BOUNCE APART)
1 of 10
What happens to the rate of a reaction if the temperature is decreased?
DECREASES
2 of 10
What happens to the rate of reaction if the concentration of the dissolved reatants is increased?
INCREASES
3 of 10
What happens to the rate of reaction if the pressure of gas reactants is increased?
INCREASES
4 of 10
What happens to the rate of a reaction if the surface area of a reactant is increased?
INCREASES
5 of 10
What does a catalyst do to the rate of reaction?
INCREASES
6 of 10
Why can catalysts be reused?
NOT USED UP DURING THE REACTION
7 of 10
How can the rate of a chemical reaction be measured?
HOW FAST THE REACTANT IS USED UP / PRODUCT IS MADE
8 of 10
Give four ways in which you could increse the rate of a chemical reaction.
INCREASE TEMPERATURE; INCREASE CONCENTRATION (PRESSURE); INCREASE STRUCTURE AREA; ADD A CATALYST
9 of 10
