Resource summary
Endo/Exo-thermic reactions
ENDOTHERMIC REACTIONS
Energy is taken in
A CHEMICAL REACTION THAT TAKES HEAT ENERGY IN, SHOWN BY A FALL IN TEMP.
As ammonium nitrate dissolves in water it takes in heat energy from its surroundings
Photosynthesis uses light energy from the sun to convert Co2 and H2O into glucose and o2
Old bonds are broken and new bonds are made
ENERGY MUST BE SUPPLIED TO BREAK EXISTING BONDS
The energy required to break old bonds in the reaction, is GREATER than the energy released when new bonds are formed in the products
EXOTHERMIC REACTIONS
A CHEMICAL REACTION IN WHICH HEAT ENERGY IS GIVEN OFF, SHOWN BY RISE IN TEMP.
Energy is given off
Burning fuels (combustion) and Explosions
Olds bonds are broken and new bonds are made
ENERGY IS released when new bonds are formed
The heat energy released in forming bonds in the products, is GREATER than the energy used in breaking old bonds in the reactants
