Question
Chapter 7, Problem 7.43AP
Interpretation Introduction
Interpretation:
The rate of forward reaction to rate of reverse reaction has to be compared for an endergonic and an exergonic reaction.
Concept Introduction:
- Activation energy: It is defined as the minimum energy required by the reacting species in order to undergo
chemical reaction . - Change in energy taking place in a reaction can be represented in a diagram called energy diagram.
- Exergonic Reaction: In a chemical reaction if the free energy is released, it is known as exergonic reaction. The free energy is released due to the losing of energy from the reactant. The value of
- Endergonic Reaction: In a chemical reaction if the free energy is absorbed, it is known as endergonic reaction. The free energy is absorbed by the reactant to form product. The value of
