An activation energy is the MINIMUM energy required for a particle to react.
A catalyst is a substance that alters the rate of a reaction BUT IS NOT USED UP in the reaction
Dynamic equilibrium is a situation in which the FORWARD AND BACKWARD REACTIONS ARE OCURRING AT THE SAME RATE.
Electrophillic addition occurs when an ALKENE is attacked by an electrophile eg. HBr
Elimination occurs when an OH ion is reacted with a HALOALKANE in a HOT ETHANOLIC mixture
Enthalpy change is a measure of HEAT ENERGY given out or took in at CONSTANT PRESSURE
Enthalpy diagrams plot ENERGY LEVELS of REACTANTS and PRODUCTS on a vertical scale
The fingerprint region is the area of an INFRA-RED SPECTRUM below 1500CM that is INDIVIDUAL TO EACH MOLECULE.
The Maxwell-boltzmann distribution shows the distribution of ENERGIES/SPEEDS of molecules in GAS/LIQUID
Mean Bond Enthalpy
Mean Bond Enthalpy is the AVERAGE ENTHALPY required to break a particular bond.
Molecular ion in MASS SPECTROMETRY is a molecule that had been IONISED but not BROKEN during spectrometry.
Nucleophillic Substitution occurs when an OH ion is reacted in a COLD AQUEOUS solution.
The oxidation state is the NUMBER of ELECTRONS LOST compared to uncombined ATOM (0).
Standard enthalpy of combustion
Standard enthalpy of combustion is the enthalpy change when 1 MOLE of a substance is completely BURNED IN OXYGEN under STANDARD STATES AND CONDITIONS.
Standard enthalpy of formation
Standard enthalpy of formation is the enthalpy change when 1 MOLE of a substance is formed from its ELEMENTS under STANDARD STATES AND CONDITIONS.
