When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.
Endergonic takes energy in to make a reaction. Exergonic releases energy when the reaction happens. An example of endergonic would be when plants use photosynthesis. Carbon dioxide and water molecules would be the reactants and when the plant absorbs energy like the sun, the turn it into sugar molecules that are high in energy. An example of an exergonic reaction would be wood burning. Heat and light is released.
The chemical energy in the reactants is almost equal to the chemical energy in the products
The reactants are Hydrogen atoms and products are Helium atoms. Because Helium atoms are larger than Hydrogen atom, large amount of energy is released from the net binding energy that resulted during the fusion process.
You have to add up the bond energies of all the bonds on the products side and the reactants side. When bonds are formed energy is released. Conversely energy has to be put into a system to break bonds (like smashing a block of ice with a baseball bat) If there is more bond energy on the products side bonds were created (energy was released) which means the reaction is exothermic. If there is more bond energy on the reactants side, bonds were broken (energy put in) and so the reaction is endothermic.
Yes, combustion is an example of an exergonic reaction. During combustion, energy is released- making it an exergonic reaction.

In an exothermic reaction the energy of the products is less than that of the reactants.

used to drive an endergonic reaction
The reaction don't have to deal with the equation
It's being released.
The chemical energy in the reactants is almost equal to the chemical energy in the products
Exergonic reactions are chemical reactions in which energy is released as heat.
Yes, cellular respiration is an example of an exergonic reaction (releasing energy for usage) as opposed to photosynthesis (the plant's need the sun's energy to create glucose) an endergonic reaction.Why? Cellular respiration breaks down glucose molecules(which contain energy), so energy is released. The reactants start with a high level of energy(the reactants are whole glucose molecules) and the products are created with a low level of energy because energy is released. The energy that is released from this process can be used to perform work in the cell.No, it releases energy.
