Thermo Chem Flashcards
Temperature
Average kinetic energy of the particles of a substance, measured in degrees Celsius
Bond energy
Amount of energy required to break a bond in one mole of the molecules in which the bond is formed, measured in KJ.mol
Heat reaction
Net change of chemical potential energy of a system during a chemical reaction, measured in KJ.mol
Heat
Form of energy also known as thermal energy measured in Joules
Exothermic reactions
Chemical reaction that transfers chemical potential energy into thermal energy
Endothermic reaction
a chemical reaction that transfers thermal energy into chemical potential energy
Activated energy/ energy absorbed
Minimum energy required to start a chemical reaction
Activated complex
High energy, unstable, temporary transition state between the reactants and the products
Catalyst
Substance that increase the rate of reaction but remains unchanged at the end of the reaction
