Question
Chapter 21.5, Problem 21.7P
Interpretation Introduction
Interpretation:
The reason why
Concept Introduction:
Oxidation: The oxidation is reaction that involves addition of oxygen atom or loss of electrons or removal of hydrogen atom present in the chemical compound.
Exergonic: The reaction is considered as exergonic if energy released since the reactants loses its energy making the free energy more negative hence making it spontaneous reaction.
Endergonic: The reaction is considered as endergonic if it needs more energy means that activation energy is much higher making the reaction non spontaneous.
