Question
Chapter 20, Problem 20TE
To determine
The ways by which it is possible to cause an endothermic reaction when the reaction causes energy to become less dispersed.
Expert Solution & Answer
Answer to Problem 20TE
The endothermic reaction takes up energy and thus it is possible to proceed when the reaction causes energy to become less dispersed.
Explanation of Solution
The process of the conversion of reactant species into the product species is called a chemical reaction.
There are two main types of
- The chemical reaction where the energy is absorbed in the system from the external area or the surrounding is the endothermic type of reaction.
- The chemical reaction where the energy is released to the surrounding from the area of interest or the system is the exothermic type of reaction.
The endothermic reaction is a process that takes up the energy to complete the process and thus it is possible to have an endothermic reaction even when the reaction is causing the energy to become less dispersed.
Conclusion:
Therefore, an endothermic reaction takes up energy and thus it is possible to proceed when the reaction causes energy to become less dispersed.
