Slide7The rates of chemical reactions can vary.
Four factors can change the rate of a chemical reaction.
1)
Concentration
of the reactant
10%
75%
Slide8The rates of chemical reactions can vary.
1)
Concentration of the reactant
2) Surface area of reactant
Four factors can change the rate of a chemical reaction.
Slide9The rates of chemical reactions can vary.
1)
Concentration of the reactant
2) Surface area of reactant
3)
Temperature
of the reaction mixture
Four factors can change the rate of a chemical reaction.
Slide10The rates of chemical reactions can vary.
Four factors can change the rate of a chemical reaction.
1)
Concentration of the reactant
2)
Surface area
of reactant
3)
Temperature
of the reaction mixture
4) Presence of a
catalystCatalyst – takes part in a reaction but is not consumed during the reaction. It decreases the energy needed to start a reaction, and increases the reaction rate.
