1 Chapter 13 - Chemical Equilibrium Intro A. Chemical Equilibrium 1. The state where the concentrations of all reactants and products remain constant with time 2. All reactions carried out in a closed vessel will reach equilibrium a. If little product is formed, equilibrium lies far to the left b. If little reactant remains, equilibrium lies far to the right 13.1 The Equilibrium Condition A. Static Equilibrium does not occur in chemical systems 1. No reaction is taking place 2. All product molecules will remain product 3. All unused reactant molecules will remain unreacted B. Dynamic Equilibrium 1. Reactions continue to take place 2. Reactant molecules continue to be converted to product 3. Product continues to be converted to reactant (reverse reaction)

AP Chemistry A. Allan Chapter 5 - Gases 5.1 Pressure A. Properties of gases 1. Gases uniformly fill any container 2. Gases are easily compressed 3. Gases mix completely with any other gas 4. Gases exert pressure on their surroundings a. Pressure = force/area B. Measuring barometric pressure 1. The barometer a. Inventor - Evangelista Torricelli (1643) 2. Units a. mm Hg (torr) (1) 760 torr = Standard pressure b. newtons/meter2 = pascal (Pa) (1) 101,325 Pa = Standard pressure c. atmospheres (1) 1 atmosphere = Standard pressure 5.2 The Gas Laws of Boyle, Charles, and Avogadro A. Boyle's Law (Robert Boyle, 1627 - 1691) 1. the product of pressure times volume is a constant, provided the temperature remains the same kPV = a. P is inversely related to V

Chapter 5: Gases Section 5.2: Pressure Sunday, October 19, 2014 12:43 PM Pressure = Force / Area ? **note: atmospheric pressure is caused by the weight of air molecules as they are attracted by gravity (hence why pressure decreases as altitude decreases) ? Measuring Pressure ? Barometer - device that measures atmospheric pressure Long tube filled with mercury, essentially you pour the mercury out of the tube until it stops because the mercury creates a seal and a vacuum in the closed end of the tube -pressure decreases cause the mercury seal to fall lower -pressure increases cause the mercury seal to fall higher ? Units of Pressure ? Pascal - (Pa) unit for pressure, equal to one Newton / meter squared --> Force / area

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 06 Dec. 2012 Brady, Jespersen, & Hyslop Chapter 11 Properties of Gases Properties of Gases Compressible Low Density Exert Pressure (temperature dependence) Expand Mixable Some common properties of gases: While bulk properties, these intimate a molecular level foundation. Properties of Gases Recall that our understanding of kinetic energy in molecular systems relies on a molecular-level picture of gases. Kinetic Theory of Gases (CH 7) Example: Pressure Units of Pressure Standard atmosphere (atm): the pressure needed to support a column of mercury 760 mm high measures at 0 ?C The SI unit of pressure is the pascal (Pa): Pressure Measurements Open-ended Mercury Manometer:

A Gas Uniformly fills any container. Mixes completely with any other gas Exerts pressure on its surroundings. A Gas It might help to define a gas based on the other phases as well. -Movie Clip- Kinetic Molecular Theory 1. Volume of individual particles is ? zero. 2. Collisions of particles with container walls cause pressure exerted by gas. 3. Particles exert no forces on each other. 4. Average kinetic energy ? Kelvin temperature of a gas. The Meaning of Temperature Kelvin temperature is an index of the random motions of gas particles (higher T means greater motion.) -Kinetic Energy Video- Pressure is equal to force/unit area SI units = Newton/meter2 = 1 Pascal (Pa) 1 standard atmosphere = 101,325 Pa 1 standard atmosphere = 1 atm = 760 mm Hg = 760 torr atm mmHg torr

Chem 110 Chapter 5 Test Review States of Matter: Gases, Liquids and Solids Changes in State Changes in state are considered physical changes. Other physical properties may also change during a change in state. 4 States of Matter are: Gases, Liquids, Solids Comparison of Physical Properties of Gases, Liquids, and Solids Property Gas Liquid Solid Volume and Shape Expands to fill the volume of its container and takes the shape of its container. Has a fixed volume at a given mass and temperature. Volume depends on its mass and temperature. It assumes the shape of its container. Has a fixed volume which is dependent on its mass and temperature. It has a definite shape. Density Compressibility Particle Motion Low High Virtually free High Very low
