Bond Energies Flashcards
What is a reaction profile?
A diagram that shows the relative energies of the products and reactants in a reaction.
And how the energy changes over he course of he reaction.
Energy on the Y axis and progress of the reaction on the x axis.
What is an endothermic reaction?
A reaction where energy is taken in to break bonds.
The energy content of the reactants is greater than the energy content of the products.
What is an exothermic reaction?
A reaction where energy is released to form bonds.
The energy content of the reactants is less than the energy content of the products.
What is activation energy?
The minimum amount of energy that reactants need to collide with each other and react.
what is the difference between the energy of the products and reactants called?
the energy absorbed.
What is enthalpy?
Heat energy stored on a chemical reaction or potential energy in a chemical reaction.
What is the symbol for enthalpy
H
What is the notation for change in enthalpy?
ΔH = H products - reactants
What is the symbol for a exothermic reaction?
-VE ΔH
What is the symbol for a endothermic reaction?
+VE ΔH
What is the unit of enthalpy?
KJ/mol
