Chemical Kinetics

Chemical Kinetics

The study of reaction rates and how they are influenced by various conditions.

Rate of Formations and Disappearances

Describes how the concentrations of reactants decrease and products increase over time in a chemical reaction.

Average and Instantaneous Rate

Average rate is the change in concentration over a finite time period, while instantaneous rate is the change at a specific moment.

Factors Affecting Reaction Rate

Parameters like concentration, nature of reactants, physical state, surface area, temperature, solvent, and catalysts that influence the speed of a reaction.

Positive Catalysts

Substances that increase the rate of a chemical reaction by lowering activation energy barriers.

Negative Catalysts

Substances that decrease the rate of a chemical reaction by increasing activation energy barriers.
