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. Must break bonds Anything that increases how often and how hard will make the reaction faster. Reactants. Energy.

Reaction Kinetics

Reaction Kinetics. A measure of the rate at which a reaction occurs. Kinetic Energy. Related to molecular speed KE = 1 / 2 mv 2 higher velocity = higher KE. Reaction Rate. The rate of reaction tells us the speed at which a reaction takes place.
