Questions & Step-by-Step Solutions
In which scenario would ΔG be zero?
Step 1: Understand what ΔG means. ΔG represents the change in free energy of a system.
Step 2: Know that ΔG can tell us if a reaction will happen or not. If ΔG is negative, the reaction can happen spontaneously. If ΔG is positive, the reaction will not happen spontaneously.
Step 3: Learn about equilibrium. Equilibrium is a state where the concentrations of reactants and products remain constant over time.
Step 4: Realize that at equilibrium, there is no net change in the amounts of reactants and products. This means the forward and reverse reactions are happening at the same rate.
Step 5: Conclude that when a system is at equilibrium, ΔG equals zero. This indicates that the system is stable and there is no driving force for the reaction to proceed in either direction.
Gibbs Free Energy (ΔG) – ΔG represents the change in free energy during a reaction, and when it is zero, the system is at equilibrium.
Equilibrium – At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction, resulting in constant concentrations of reactants and products.
