Reaction Rate

Reaction Rate. How Fast Does the Reaction Go. Collision Theory. In order to react molecules and atoms must touch each other. They must hit each other hard enough to react. Anything that increase these things will make the reaction faster. Reactants. Energy. Products. Reaction coordinate.

Entropy

Entropy . Explanation and theory. What is Entropy?. Entropy is the measure of the disorder of a system. Ex, When a liquid turns into gas by heating it, the intermolecular forces decrease and the speed of the particles increase . The particles become more disordered . .
