Questions & Step-by-Step Solutions
In a spontaneous process, the change in Gibbs free energy (ΔG) is:
Correct Answer: negative
Step 1: Understand what a spontaneous process is. A spontaneous process is a reaction or change that occurs naturally without needing to be driven by an external force.
Step 2: Learn about Gibbs free energy (ΔG). Gibbs free energy is a measure of the energy available to do work in a system at constant temperature and pressure.
Step 3: Know the relationship between spontaneity and ΔG. For a process to be spontaneous, it must release energy, which is indicated by a negative ΔG.
Step 4: Remember the rule: If ΔG is negative, the process is spontaneous. If ΔG is positive, the process is non-spontaneous.
