Frequently Asked Questions
What is activation energy?
Activation energy (Ea) is the minimum energy required for reactant molecules to undergo a chemical reaction. It represents the energy barrier that must be overcome for bonds to break and new bonds to form.
How does a catalyst affect activation energy?
A catalyst lowers the activation energy by providing an alternative reaction pathway. This increases the rate constant and reaction rate without being consumed in the reaction.
