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.

Reaction Kinetics

Reaction Kinetics. The Kinetic Theory of Matter. The Kinetic Theory of Matter states that matter is composed of a large number a small particles—individual atoms or molecules—that are in constant motion. This constant motion is the reason that chemical reactions occur. Kinetics .

Reaction Kinetics

Reaction Kinetics. The rate at which a reaction occurs. Kinetic Energy. Related to molecular speed KE= ½ mv 2 Higher velocity (faster)= higher energy. Reaction Rate. The rate of reaction tells the speed at which the reaction takes place. Collision Theory.

Reaction Kinetics

Reaction Kinetics. In chemistry, we care not only about what reacts, but also how fast . Black powder explodes in a flash, while the sugar in your coffee never seems to dissolve fast enough. We try to speed up environmental cleanup and retard rust and aging. In other words, rates matter !.

Reaction Kinetics

Reaction Kinetics. Reaction Rates The rate of a reaction is usually expressed in terms of a change in concentration of one of the participants per unit time. rate = [ ] t It is the speed at which reactants are converted into products

Reaction Kinetics

Reaction Kinetics. aA + bB  cC + dD. Rate (r) = -(1/a) (d[A]/dt) or -(1/b) (d[B]/dt) or …. +(1/c) (d[C]/dt) or +(1/d) (d[D]/dt). Reaction rates are followed by monitoring the rate of disappearance of reactants or the rate of appearance of products.

Kinetics (Reaction Rate)

Kinetics (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 with enough force and with the correct orientation . The more “frequently” the particles hit, the faster the reaction will go.
