Answer:
Exothermic reaction
Explanation:
Energy diagrams can help us determine how the energy of reactants changes throughout a reaction.
Energy Diagrams
The purpose of energy diagrams is to show how the energy of reactants and products changes over time.
In the diagram, A is the activated complex. This is the intermediate compound that forms from the reactants before the products are made.
B is the activation energy. This is the amount of energy required for the reaction to occur.
C is the energy of reaction. This is the energy that a reaction absorbs or releases.
Energy of Reaction
Exothermic reactions release energy, and endothermic reactions absorb energy. This means that in exothermic reactions the reactants have higher energy than the products. On the other hand, in endothermic reactions, the reactants are lower energy than the product. In this reaction, the reactants are higher energy, so the reaction is exothermic. This means that energy is released, and the energy of reaction will be negative.
Catalyst
A catalyst is a compound that can be added to a reaction to increase the rate of reaction. Catalysts increase the rate of reaction by decreasing the activation energy. This makes the reaction more likely to occur and speeds up the reaction. Catalysts also decrease the energy of the activated complex.
