pure liquid-vapour equilibrium - Theoretical and Computational
... Part of the shaded area, up to the normal boiling point, Tb, of the liquid, is the subject of this experiment in which the vapour pressure dependence on temperature will be investigated. This dependence can be related to the enthalpy of vapourisation Hvap in the following way. For equilibrium betwee ...

Measuring Rates
... The integrated rate law for a chemical reaction expresses how the concentration of a relevant reacting species changes as a function of time. Thus, it can be used to predict the time it will take for a reactant or product to reach a given concentration, or to predict such concentration at a selected ...

... Chemical kinetics is the quantitative study of chemical systems that are changing with time. (Thermodynamics, another of the major branches of physical chemistry, applies to systems at equilibrium—those that do not change with time.) In this course, we will restrict our attention to systems that are ...

Equilibrium chemistry
Equilibrium chemistry is a concerned with systems in chemical equilibrium. The unifying principle is that the free energy of a system at equilibrium is the minimum possible, so that the slope of the free energy with respect to the reaction coordinate is zero. This principle, applied to mixtures at equilibrium provides a definition of an equilibrium constant. Applications include acid-base, host-guest, metal-complex, solubility, partition, chromatography and redox equilibria.
