Interplay of Enthalpy and Entropy

Table 3.3 summarizes how the balance between enthalpy and entropy determines the direction in which a process is thermodynamically favorable. However, keep in mind the following:

> 1. The favorability of a process (negative ) has nothing to do with reaction rate.

> 2. The entropy of an open system can decrease, but energy must be expended to do so, however.
