The subject is the continuation of the course General chemistry I. The main attention is paid to general principles governing chemical processes. Using various examples, the fact that the validity of these principles is not restricted only to chemical processes is documented. The significance and practical use of explained principles are illustrated by examples solved in exercises.
Chemistry knowledge at the level of the subject General chemistry I.

1. The scope of chemical thermodynamics, thermodynamic description of the
the state of a system and its changes, standard states, state functions and
their properties, internal energy, enthalpy, the first law of thermodynamics,
introducing of the concept of reversible / irreversible processes illustrated on
the example of the isothermal volume change of an ideal gas.

thermochemistry, the heats of chemical reactions, the heats of phase
transitions, thermochemical calculations.

second law of thermodynamics and its consequences, introducing of the state
function Gibbs energy.

composition on the time, first order reactions, selected systems of the first
order reactions, their similarities with the relations describing the kinetics
of radioactive decay.

reactions of higher order.

- Study Objective:
The students of non-chemical specializations gain sufficient knowledge in general principles governing chemical processes (reactions).
Graduate of this course is able to decide, whether a process will take place under given condition and what will be its result.
