REACTANT + REACTANT  PRODUCT(S) REACTANT + REACTANT  PRODUCT(S) Reactions A process that changes one set of chemicals into another set of chemicals. Chemical reactions always involve changes to the chemical bonds that join atoms in compounds. REACTANT + REACTANT  PRODUCT(S) REACTANT + REACTANT  PRODUCT(S)

Reactions Exothermic Reaction Exothermic reaction Chemical reactions that release energy often occur spontaneously (automatically)

Reactions Endothermic Reaction Endothermic reaction Chemical reactions that absorb energy will not occur without a source of energy

What are spontaneous reactions? spontaneous reactions occur naturally

Is the energy required for a reaction to start. Reactions Activation Energy Is the energy required for a reaction to start. Some reactions need to have energy added to start them Called activation energy

Reactions Hydrogen peroxide ( H 2 O 2 ) is stored in dark bottles to keep light out. If hydrogen peroxide ( H 2 O 2 ) is left outside it will release oxygen and eventually turn into water ( H 2 O). Sometimes the amount of activation energy needed is too high and the reactions will not occur fast enough We have a way of overcoming this problem-enzymes

How come the reaction will not occur faster? Reactions How come the reaction will not occur faster? Some reactions need to have energy added to start them Called activation energy

Reactions Sometimes the amount of activation energy needed is too high and the reactions will not occur fast enough We have a way of overcoming this problem-enzymes

Reactions The hydrogen peroxide turned into water ( H 2 O) and oxygen ( O 2 ). What was different about THIS reaction? Sometimes the amount of activation energy needed is too high and the reactions will not occur fast enough We have a way of overcoming this problem-enzymes

Reactions Some reactions need to have energy added to start them Called activation energy

A catalyst speeds up the rate of a chemical reaction. reactions A catalyst speeds up the rate of a chemical reaction.

A catalyst lowers the activation energy. reactions A catalyst lowers the activation energy.
