Chemical Kinetics

Chemical Kinetics

Chemical Kinetics. The area of chemistry that concerns reaction rates and reaction mechanisms . Reaction Rate. The change in concentration of a reactant or product per unit of time. 2NO 2 (g)  2NO(g) + O 2 (g) . Reaction Rates:. 1. Can measure disappearance of reactants.

Kinetics

Kinetics. Brainstorm: What are some factors that affect the rate of a reaction?. Reaction Rate. Change in [reactants] or [products] per unit time (M/s) Always expressed as a positive quantity Can be expressed as appearance of B OR disappearance of A. A  B. Changes in reaction rate.

Types of Rate Laws

Types of Rate Laws. First Order Second Order Zero Order. Why study rate laws?. Can work backwards from the rate law to infer steps by which the reaction occurs Most reactions do not occur in a single step Most result from a series of steps.
