CY8151 ENGINEERING CHEMISTRY

(Common to all branches of B.E. / B. Tech. Programmes)

UNIT I CHEMICAL THERMODYNAMICS

Second law:  Entropy - entropy change for an ideal gas, reversible and irreversible processes;
entropy of phase transitions; Clausius inequality.  Free energy and work function: Helmholtz and
Gibbs free energy  functions; Criteria of spontaneity; Gibbs-Helmholtz equation; ClausiusClapeyron equation; Maxwell relations – Van‟t Hoff isotherm and isochore.  Chemical potential;
Gibbs-Duhem equation – variation of chemical potential with temperature and pressure.

UNIT II POLYMER CHEMISTRY

Introduction: Classification of polymers – Natural and Synthetic; Thermoplastic and

Thermosetting. Functionality –  Degree of polymerisation. Types and mechanism of
polymerisation: Addition  (Free Radical, cationic, anionic and living); condensation and
copolymerisation. Properties of polymers: Tg, Tacticity, Molecular weight – weight average,
number  average  and  polydispersity  index. Techniques  of  polymerisation:  Bulk,  emulsion,
solution and suspension.

UNIT III KINETICS AND CATALYSIS

Introduction  –  reaction  velocity,  factors  affecting  reaction  velocity,  rate  constant,  order  of
reaction, molecularity, pseudo molecular reactions, zero, first, second and third order reactions,
reactions of fractional orders, determination of order of reactions. Catalysis:   Auto catalysis -
Enzyme Catalysis: Michaelis-Menton equation; factors affecting enzyme catalysis.
Heterogeneous Catalysis: Types of adsorption isotherms: Langmuir–Hinselwood and Rideal–
Eley Mechanism.

UNIT  IV PHOTOCHEMISTRY AND SPECTROSCOPY 

Photochemistry: Laws of photochemistry - Grotthuss–Draper law, Stark–Einstein law and
Lambert-Beer Law. Photoprocesses - Internal Conversion, Inter-system crossing, Fluorescence,
Phosphorescence, Chemiluminescence and Photo-sensitisation. Spectroscopy:
Electromagnetic spectrum - Absorption  of radiation – Electronic, Vibrational and rotational
transitions. Width and intensities of spectral lines. Spectrophotometric estimation of iron. UV visible and IR spectroscopy – principles, instrumentation (Block diagram) and applications.

UNIT  V NANOCHEMISTRY 

Basics - distinction between molecules, nanoparticles and bulk materials; size-dependent
properties. Nanoparticles: Nanocluster,  nanorod,  nanotube  and  nanowire. Synthesis:
Precipitation, thermolysis, hydrothermal, solvothermal, electrodeposition, chemical  vapour
deposition,   laser   ablation;   Properties   and   Applications. Risk   discussion   and   Future
perspectives.
