Chapter 38, Problem 18RQ
Summary Introduction
To determine: The reason for an example of the second law of
Introduction: The second law of thermodynamics is all about entropy that can never be reduced. Entropy always remains positive. The pyramid of energy is based on the second law of thermodynamics.

Living organisms increase in complexity as they grow, resulting in a decrease in the entropy of an organism. How does this relate to the second law of thermodynamics?
The first and second laws of thermodynamics are useful for biochemists who investigate chemical reactions in living organisms. Explain why the third law is not useful.
Why is it not enough to just rely on either thermodynamic data alone ... Or
kinetic (rate of reaction) data alone
to predict the possible occurrence of a chemical reaction?
