WHAT IS A CHEMICAL REACTION?
A PROCESS IN WHICH A COVALENT OR IONIC BOND IS FORMED OR BROKEN
WHAT DOES A CHEMICAL EQUATION LOOK LIKE?
SHOWS THE REACTANTS ON THE LEFT AND THE PRODUCTS ON THE RIGHT AND AN ARROW POINTING FROM THE REACTANTS TO THE PRODUCTS
CHEMICAL REACTIONS CAN BE CLASSIFIED BY WHAT 3 THINGS?
1. DECOMPOSITION
2. SYNTHESIS
3. EXCHANGE REACTIONS
WHAT IS DECOMPOSITION?
A LARGE MOLECULE BREAKS DOWN INTO 2 OR MORE SMALLER ONES.

AB-> A+B
WHAT IS SYNTHESIS?
SYNTHESIS IS THE OPPOSITE OF DECOMPOSITION, 2 OR MORE SMALLER MOLECULES COMBINE TO FORM A LARGER ONE

A+B-->AB
WHAT IS EXCHANGE REACTIONS?
2 MOLECULES EXCHANGE ATOMS OR GROUPS OF ATOMS
AB+CD-->AC+BD
WHAT IS THE LAW OF MASS ACTION?
REVERSIBLE REACTIONS PROCEED FROM THE SIDE WITH THE GREATER QUANTITY OF REACTANTS TO THE SIDE WITH THE LESSER QUANTITY
WHAT IS EQUILIBRIUM?
RATIO OF PRODUCTS TO REACTANTS IS STABLE
HOW CAN EQUILIBRIUM BE UPSET?
BY A SURPLUS OF HYDROGEN IONS WHICH DRIVE THE REACTION TO THE LEFT OR CARBON DIOXIDE AND DRIVING IT TO THE RIGHT
WHAT ARE SOME FACTORS THAT AFFECT REACTION RATES?
1. CONCENTRATION
2. TEMPERATURE
3. CATALYSTS
HOW DOES CONCENTRATION AFFECT REACTION RATES?
REACTION RATES INCREASE WHEN REACTANTS ARE MORE CONCENTRATED. BECAUSE MOLECULES ARE MORE CROWDED AND COLLIDE MORE FREQUENTLY
HOW DOES TEMPERATURE AFFECT REACTION RATES?
REACTION RATES INCREASE AS TEMPERATURE RISES BECAUSE HEAT CAUSES THE MOLECULES TO MOVE MORE RAPIDLY AND COLLIDE WITH GREATER FORCE AND FREQUENCY
WHAT IS A CATALYST?
ANY CHEMICAL THAT LOWERS THE ACTIVATION ENERGY OF A CHEMICAL REACTION AND MAKES THE REACTION PROCEED MORE RAPIDLY; A ROLE SERVED IN CELLS BY ENZYMES
METABOLISM HAS WHAT 2 DIVISIONS?
1. CATABOLISM
2. ANABOLISM
WHAT IS CATABOLISM
CONSISTS OF ENERGY RELEASING DECOMPOSITION REACTIONS
WHAT ARE ENERGY RELEASING REACTIONS CALLED?
EXERGONIC REACTIONS
WHAT IS ANABOLISM
CONSISTS OF ENERGY STORING SYNTHESIS REACTIONS
WHAT ARE ENDERGONIC REACTIONS?
REACTIONS THAT REQUIRE AN ENERGY INPUT SUCH AS SYNTHESIS REACTIONS
