Rank the substances involved in this reaction in the order of decreasing potential energy:
1 answer:
The answer is- The order of decreasing potential energy is :
The potential energy can be expressed as the static energy that is stored in the chemical bonds.
What is the trend of potential energy in an exothermic reaction and an endothermic reaction?
- During an exothermic reaction, heat is released and the stored potential energy of bonds is converted into the kinetic energy and thus there is a decrease in the potential energy during an exothermic reaction.
- During an endothermic reaction, heat is absorbed during the reaction and this heat is stored as potential energy in bond, hence the potential energy increases during a endothermic reaction.
- Now, during this reaction, basic Magnesium hydroxide,
reacts with acidic
, thus this reaction is an exothermic reaction.
- Hence, the potential energy of products is less than the potential of reactants.
- Next, the potential energy of solids are always more than the potential energy of gases.
- Therefore, the decreasing order of potential energy is
[H2O is not considered]
