Learning Goal: To understand how to calculate the equilibrium constants for chemical equations that can be produced by the addition of other chemical equations with known equilibrium constants. For a chemical reaction equation with the general form aA+bB⇌cC+dD the equilibrium equation is given by K1=[C]c[D]d[A]a[B]b Thus, for a chemical reaction equation with the general form cC+dD⇌eE+fF the equilibrium equation is given by K2=[E]e[F]f[C]c[D]d If the first two equations are added together such that aA+bB⇌eE+fF then the equilibrium equation is given...

Phase transitions are similar to chemical reactions in that they
each have an associated entropy change. A phase transition involves
the breaking or forming of intermolecular attractive forces.
A change in entropy accompanies not only a variation in the
temperature, pressure, or volume of a system but also a physical
transformation such as the fusion, vaporization, or transition from
one crystalline state into another.
In the equilibrium between two phases, the exchange of heat can
be carried out reversibly, and...

1. One way to solve chemical equilibrium problems is to write n equations with n unknowns, and then to eliminate unknowns from equations until you have one equation of order n. To solve such an equation involves something like using the quadratic formula (if n = 2) or some other algorithm if n > 2. One such algorithm is the Newton Raphson technique. Let’s pretend that you are solving an equilibrium problem and you have derived the following equation which...
