Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is a reaction mechanism?A reaction mechanism is a step-by-step story that shows how molecules change. It tells us which bonds break, which bonds form, and the tiny, short-lived pieces called intermediates that appear along the way. It also shows the highest-energy point, called the transition state, that the reaction must reach.
2. Why do chemists study reaction mechanisms?Chemists study mechanisms so they can control reactions. By knowing the steps, they can make the reaction work faster, choose the right products, and avoid making unwanted waste. This helps make medicines, materials, and energy cleaner.

Elementary Step: A single molecular event in a reaction mechanism, such as a bond breaking or forming.
Transition State: A high-energy, unstable arrangement of atoms that exists momentarily during a chemical reaction.
Activation Energy: The minimum amount of energy required for reactants to overcome the energy barrier and form products.
Computational Chemistry: The use of computer simulations to study chemical phenomena and predict reaction pathways.
