Questions & Step-by-Step Solutions
What does a positive ΔG indicate about a reaction?
Step 1: Understand what ΔG means. ΔG is the change in free energy of a reaction.
Step 2: Know that a positive ΔG value means the energy of the products is higher than the energy of the reactants.
Step 3: Recognize that if a reaction has a positive ΔG, it requires energy to occur.
Step 4: Conclude that a reaction with a positive ΔG is non-spontaneous, meaning it will not happen on its own without added energy.
Gibbs Free Energy (ΔG) – ΔG is a thermodynamic potential that indicates the spontaneity of a reaction; a positive ΔG means the reaction requires energy input to proceed.
