Statement Analysis: Statement 1: Entropy is a measure of disorder. Thus, if there is an increase in order there is a decrease in entropy. Statement 2: The greater the entropy of a system, the smaller its free energy. Thus, an increase in entropy during a reaction will result in a decrease in free energy. A. Both statements are true B. Only statement 1 is true. C. Only statement 2 is true. D. Neither of the statement is true.

Why does the product (a•b), rather than the sum (a + b) appear in the Law of Mass Action? This is sometimes brought up to demonstrate how/why nonlinear terms arise in differential equations. The law of mass action states that The rate of a chemical reaction involving an interaction of two or more chemical species is proportional to the product of the concentrations of the given species. This is NOT an assignment...I'm just curious and trying to understand mathematical relations better. Thanks!
