Chemistry- Enthalpy Flashcards
Definition of Enthalpy
thermal energy that is stored in a system
Definition of enthalpy change
the heat energy change at a constant pressure
Equation for enthalpy change
enthalpy products - enthalpy reactants
Definition of enthalpy change of reaction
the energy change associated with a given reaction
definition of enthalpy change of formation
energy change that takes place when 1 mole of a compound is formed from its consistent elements in their standard state under standard conditions
definition of enthalpy change of combustion
the energy change that takes place when 1 mole of a substance is completely combusted
definition of enthalpy change of neutralisation
the energy change with the formation of 1 mole of water from a neutralisation reaction under standard conditions
equation for enthalpy change of a reaction
total energy to break bonds - total energy to make bonds
equation for energy change
q=mcΔt
