Solution Steps

Step 1: Understanding Exergonic Reactions

An exergonic reaction is a type of chemical reaction where the change in free energy is negative. This means that the reaction releases energy to the surroundings, making it spontaneous under constant temperature and pressure.

Step 2: Analyzing the Free Energy Change

The free energy change, denoted as \(\Delta G\), is a measure of the amount of work a system can perform. For exergonic reactions, \(\Delta G\) is negative, indicating that the system releases energy.

Final Answer

The free energy change for an exergonic reaction is negative. Therefore, the answer is \(\boxed{\text{It is negative.}}\)
