A process is feasible if ΔH is positive and ΔS is negative

Text Solution

AI Generated Solution

To determine whether a process is feasible when ΔH is positive and ΔS is negative, we need to analyze the Gibbs free energy change (ΔG) for the process. The feasibility of a process is determined by whether ΔG is negative (spontaneous) or positive (non-spontaneous). ### Step-by-Step Solution: 1. **Understanding the Gibbs Free Energy Equation**: The Gibbs free energy change (ΔG) is given by the equation: \[ ΔG = ΔH - TΔS ...
