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.

What is the sign of the enthalpy change for an endothermic reaction?
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
Explain what it means for a reaction to be endothermic and what would happen to the temperature recorded by a thermometer in an endothermic reaction?
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.
Which is the best term to describe a chemical reaction in which the reactants have more potential energy than the products?
Mrs. Winn. eh?- is called an endothermic reaction.
In exothermic reactions the energy required to break the bonds in the reactants is greater than the energy released as the products form?
Exothermic reaction
An energy diagram shows the reactants having greater energy than the products illustrates what?
This shows that the reaction is endothermic because energy is absorbed in the reaction and not produced.
Do endothermic reaction have reactants with more energy than its products?
Kinetic energy has more energy than products.
which of the following describes an endothermic reaction?
Hf, products > hf, reactants
What is the sign for Energy change of an endothermic reaction?
The products of the reaction will have less energy than the reactants
The elements or compounds produced by a chemical reaction are known as what?
The substances produced by a chemical reaction are known as Products. The substances that are reacted are the Reactants.
What is a type of chemical reaction where the energy of the products is less than the energy of the reactants?
When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
An endothermic reaction is one in which heat is transferred from the surroundings to the reactants.?
Yes, this affirmation is true.
What is the best term to describe a chemical reaction in which the reactants have less potential energy than the products?
A chemical reaction whose reactants have less potential energy than the products would be called an endothermic reaction.
Do reactants and products break during a chemical reaction?
In a reaction, the bonds in reactants are broken down (endothermic) and new bonds formed. The new bonds formed (exothermic) will result in the formation of the products.
Will there be a reaction if all reactants and possible products are aqueous?
Yes, between reactive chemicals there is likely to be a reaction which will lead to precipitation if all the reactants and possible products are aqueous. The reactants, although aqueous, could fail to react if they are endothermic.
What is the sign of the enthalpy change for an endothermic reaction?

What is the criteria in terms of temperature changes for exothermic and endothermic reactions?
Endothermic reactions draw heat from the reactants / products and the environment, so they tend to get cooler as the reaction proceeds. Exothermic reactions release heat to the reactants / products and the environment, so they tend to get hotter as the reaction proceeds.
