Exothermic reaction definition
Exothermic reaction definition
Reaction that releases energy to surroundings
Products vs reactants energy (exothermic)
Products vs reactants energy (exothermic)
Products have lower energy than reactants
Surroundings temperature (exothermic)
Surroundings temperature (exothermic)
Temperature increases
Reaction profile pattern (exothermic)
Reaction profile pattern (exothermic)
Downhill - reactants higher, products lower energy
Combustion as exothermic example
Combustion as exothermic example
Burning reactions giving out heat and light
Oxidation as exothermic example
Oxidation as exothermic example
Substances react with oxygen (e.g. rusting)
Neutralisation as exothermic example
Neutralisation as exothermic example
Acids and alkalis react, produces heat
