We Can Calculate Whether a Reaction Is Spontaneous by Calculating

Multiple Choice

We can calculate whether a reaction is spontaneous by calculating the change in free energy and accounting for entropy. Your paycheck always lists your gross pay, net (take home) pay, and tax withholdings. Which of the following best correlates your paycheck to the changes in free energy?

A) gross salary = net salary - tax; total energy = free energy - entropy
B) net salary = gross salary - tax; free energy = total energy - entropy
C) tax = gross - net salary; entropy = total energy - free energy
D) gross salary = tax - net salary; total energy = entropy - free energy
E) net salary = gross salary + tax; free energy = total energy + entropy
