Enthalpy Flashcards
Exothermic and enthalpy
The energy product is less than the energy content of the reactants
Enthalpy and endothermic
The energy content of the product is grater content of the reactants
How to calculate the enthalpy
Reactant - products
Catalyst and enthalpy
A catalyst will speed up the reaction by providing an alternative pathway with a lower activation energy, the enthalpy change is not altered by the use of a catalyst
What is the activated complex
The activated complex represents an intermediate stage between the reactants and products
Where is the activated complex formed
It is formed at the top of the activation energy barrier and because of it’s high energy is very unstable
What is the enthalpy of combustion
The enthalpy of combustion is when one mole of a substance completely burns in oxygen
What is enthalpy of solution
The enthalpy of solution is when one mole of a substance completely dissolves in water
What is the enthalpy of neutralisation
The enthalpy of solution is when one mole of water is formed from a neutralisation reaction
