The objectives of Physical Chemistry: Concepts and Theory are presented. The book is organized in accordance with the mathematics used: continuum for thermodynamics; discrete for quantum theory; statistics and probabilities for statistical mechanics; and the mathematics for potential-driven changes at short and long times for kinetics.

Continuation of lecture on the Variation Method. The linear variational technique is discussed using a simple example, where a 2x2 secular determinant is us

2. Chemical adsorption (chemisorption): If the force of attraction existing between adsorbate and adsorbent are almost same strength as chemical bonds, the adsorption is called chemical adsorption. CHEMISTRY MODULE PAPER:2, PHYSICAL CHEMISTRY-I : 31, Hückel Molecular orbital Theory – Application PART I 1. Learning Outcomes After studying this module, you shall be able to Appreciate the simplification introduced by E Hückel for studying organic conjugated molecules. Finally, the Variation Theory is used as a guiding principle of pedagogical design (V3).

Therefore, students may not learn effectively if they are not aware of things in exactly the same way as the teacher (Lo, 2012). However, the theory is suitable to improve learning by Many physical laws can be derived from variational principles; depending on one’s taste this may be viewed as simply convenient or deeply signiﬁcant. An important example is provided by optics. The velocity vof a photon in a medium is related to its velocity in a vacuum cby the indexofrefractionn= c/v.

Variation Theory Variation theory explains that individuals see, understand, and experience the world from their own perspectives (Orgill, 2012). Therefore, students may not learn effectively if they are not aware of things in exactly the same way as the teacher (Lo, 2012). However, the theory is suitable to improve learning by

principle and the perturbation theory, which have different applications. In this lec - is essential in physical chemistry, so we put it in the optional materials. The physical-chemical basis of phenotypic randomness or noise is explored and a theory is proposed that associates noise with random molecular motion.

To understand this we can consider the general mechanism of electron transfer to an electrode. Consider an electrolyte in which an inert or noble electrode is kept immersed. It is called working electrode, (). Also assume that an oxidised Physical Changes . Physical changes are concerned with energy and states of matter.
