Chemical Equilibrium

Chemical Equilibrium

Chemical Equilibrium. Brown, LeMay Ch 15 AP Chemistry Monta Vista High School. 15.1: Chemical Equilibrium. Occurs when opposing reactions are proceeding at the same rate Forward rate = reverse rate of reaction Ex: Vapor pressure: rate of vaporization = rate of condensation

Types of Rate Laws

Types of Rate Laws

Types of Rate Laws. Differential Rate Laws i.e. The rate law or rate equations Rate is given as a function of concentration of reactants Takes the form for A + B --> C rate = k[A] a [B] b use inital rate data to determine order with respect to each reactant rate constant.

Rates and Rate Laws

Rates and Rate Laws

Rates and Rate Laws. Reaction Rate. The change in concentration of a reactant or product per unit of time. Reaction Rates:. 2NO 2 (g)  2NO(g) + O 2 (g). 1. Can measure disappearance of reactants. 2. Can measure appearance of products. 3. Are proportional

Why do some reactions happen and others don’t?

Why do some reactions happen and others don’t?

Why do some reactions happen and others don’t?. Are the products more stable than the reactants? Thermodynamics. Does the reaction go at a reasonable rate? Kinetics. What would affect how fast a reaction happens?. Control of Reactivity.

Kinetics

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.
