Dr. M. Zewail UNIT V-ACID-BASE EQUILIBRIUM
A) IONIZATION OF WEAK ACIDS The extent to which an acid ionizes in aqueous medium can be expressed by the equilibrium constant, Ka, for the ionization reaction:
H3O+ (aq) + C2H3O2- (aq) HC2H3O2 (aq) + H2O (l) Ka
The Truth about Enthalpy
1. Enthalpy is an extensive property. 1. H for a reaction in the forward direction is equal in size, but opposite in sign, to H for the reverse reaction. 2. H for a reaction depends on the state of the products and the state of th
The ability to do work or transfer heat.
Heat: The flow of energy from a hotter object to a cooler object. Work: Energy used to cause an object that has mass to move.
Two forms of energy
Potential Energy Kinetic Energy
First Law of Thermod
All of the particles of a gas are not moving at the same speed at a given temperature.
abbreviated as rms can be represented by u a type of calculated speed not quite the same as the average speed most importantly-it is related to
Its back again. Given 2H2O2 (g) O2 (g) + 2H2O (g) , what mass of H2O2 should be used to produce 3.00 L of O2 gas measured at 25.0 C and 1.00 atm? Given 2KClO3 (s) 2KCl (s) + 3O2 (g) , calculate the volume of oxygen gas produced at 35.0 C an
Combined Gas Law
10.0 L of carbon dioxide at 6.40 atm and 8.00 C is warmed to 25.00 C at 3.00 atm. What is the new volume of the gas?
Combined Gas Law
A sample of gas at 25.0 C occupies a cylinder with a piston has a volume of 7.25 L and a pressure of 4.5
