Transcript of 06.03 chemical reaction and energy

06.03 Chemical Reactions and Energy
Exothermic
Reaction
Endothermic
Reaction
release of energy
Examples
welding
when rust of metal
formation of snow in clouds
mixing water with calcium chloride
absorption of energy
Example
melting ice cubes
evaporation of water
conversion of frost to water vapor
Heat Transferred
radiation
conduction
convection
they both are related with energy/heat
they both effect the environment
Thermodynamics; physics, chemistry.
has an opposite effect

Chemical Reaction
Three of the factors that chemical reactions depends on are temperature, concentration, and catalysts and inhibitors.
"An increase in temperature will increase the rate of reaction"
"A decrease in temperature will decrease the rate of reaction"
"Catalysts increase the rates of reactions"
"Inhibitors decrease the rates of reactions"
