Chemical Kinetics - Topic 6

Why do chemical reactions occur?

They are a result of collisions of sufficient energy and proper orientation

What is rate of reaction?

The change in concentration of reactant/the product per unit of time

How can concentration changes in a reaction be monitored?

By mass, volume, and colour

What is activation energy?

Activation energy (Ea) is the minimum energy that colliding molecules need in order to have successful collisions leading to a reaction

What does a catalyst do in a reaction?

It increasing the rate of a chemical reaction without changing itself, specifically by decreasing the Ea
