Question
Chapter U5.109, Problem 5E
Interpretation Introduction
Interpretation: Energy diagram for the oxidation of copper and its reverse reaction needs to be explained.
Concept Introduction: Oxidation of metal is exothermic. So, oxidation reactions are a potential source of energy for our daily lives. To explore the usefulness of metal oxidation as an energy source, we must examine and compare the amount of thermal energy transferred during these reactions.
Expert Solution & Answer
Answer to Problem 5E
Oxidation of copper and its reverse reaction energy diagram is
Explanation of Solution
Oxidation reactions are good source of energy because they are always exothermic. So, oxidation reactions are a potential source of energy for our daily lives. Energy diagram of oxidation of copper is as follows:
Reverse reaction energy diagram of copper is as follows:
Decomposition of CuO is highly endothermic.
Conclusion
When an oxidation reaction for a metal is reversed, the resulting products are a pure metal and oxygen gas. This reaction is termed as decomposition reaction.
