When is delta G negative?
Understand the Problem
The question is asking for the conditions under which the Gibbs free energy change (ΔG) is negative, indicating that a process or reaction is spontaneous.
Answer
Delta G is negative when the reactants have more free energy than the products, indicating a spontaneous reaction.
The final answer is that delta G (ΔG) is negative when the reactants have more free energy than the products, indicating a spontaneous reaction
Answer for screen readers
The final answer is that delta G (ΔG) is negative when the reactants have more free energy than the products, indicating a spontaneous reaction
More Information
A negative ΔG value means the reaction can occur without the input of energy, making it exergonic or spontaneous.
Tips
A common mistake is confusing the spontaneity with the speed of the reaction. A negative ΔG indicates the reaction is thermodynamically favorable, not how fast it will proceed.
