An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.
It shows whether the reaction is exothermic or endothermic.
The different in energy between the products and reactant is known as enthalpy of the reaction, or ∆Hreaction.
... is an exothermic reaction (opposite of 'endothermic')
When water freezes, it will go through an exothermic reaction, which is a chemical reaction that releases energy in the form of light or heat. It is expressed in a chemical equation as: reactants --> products + energy
Kinetic energy has more energy than products.
The products of the reaction will have less energy than the reactants
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
A chemical reaction whose reactants have less potential energy than the products would be called an endothermic reaction.
Yes, this affirmation is true.
Exothermic reaction
The potential energy of the products is greater than the potential energy of the reactants.
The products of an endothermic reaction are less chemically stable. They required an input of energy to create so naturally they are at a higher energy state.
This shows that the reaction is endothermic because energy is absorbed in the reaction and not produced.
In an exothermic reaction the reactants release energy to the environment when they react - like coal burning. In an endothermic reaction the reactants need to absorb energy from their environment when they react, so the reaction feels cold in your hand, or else you have to heat it continually to make it react. The products would then be at a higher energy level than the reactant were. Photosynthesis is an interesting example of an endothermic reaction, because in this example the energy supplied to make the reaction go is not heat but light. The product (sugar) is an 'energy store' which the plant (or whatever eats the plant) can use later on to release the energy in respiration.
The potential energy of the products is greater than the potential energy of the reactants.
An endothermic reaction absorbs heat energy from the system. In an endothermic reaction a thermometer measuring the reactants and products would register a decrease in temperature.
