★ Must-know
📌 Thermodynamics predicts whether a reaction is feasible, whereas chemical kinetics determines how rapidly the reaction occurs and under what conditions its rate changes.
Further detail
Thermodynamics asks whether; kinetics asks how fast.
1. Which field of chemistry examines reaction rates, the factors that control them, and the mechanisms by which reactions occur?
2. A reaction has a negative Gibbs free-energy change at constant temperature and pressure but proceeds imperceptibly slowly. What does this illustrate?
3. How is the rate of disappearance of a reactant related to the rate of appearance of a product in a reaction such as ?
What does chemical kinetics study in chemistry?
Reaction rates, factors controlling them, and reaction mechanisms.
What does thermodynamics predict about a chemical reaction?
Whether the reaction is feasible.
What does chemical kinetics determine about a reaction?
How rapidly the reaction occurs and how its rate changes under conditions.
What is true about a reaction with ΔG < 0 at constant temperature and pressure?
It is thermodynamically feasible.
Why does diamond-to-graphite conversion remain imperceptibly slow?
Because the reaction is kinetically slow despite being thermodynamically feasible.
What is reaction rate in chemistry?
It is the change in concentration of a reactant or product per unit time.
