The minimum amount of energy that particles must collide with to react.
What is an Endothermic Reaction?
A reaction that takes in energy from the surroundings so the temperature of the surroundings decreases. The energy needed to break existing bonds is greater than the energy released from forming new bonds.
What is an Energy Profile?
A graph used to show the relative energies of reactants and products, the activation energy and the overall change of a reaction.
What is an Exothermic Reaction?
A reaction that transfers energy to the surroundings so the temperature of the surroundings increases. The energy released from forming new bonds is greater than energy needed to break existing bonds.
What is the Overall Energy Change of the Reaction?
The difference between the sum of the energy needed to break bonds in the reactants and the sum of the energy released when bonds in the products are formed.
