Abstract:
A summary of the kinet ics of chemical and electro-chemical
reactions are discussed.
lhe next Chapter on Discussion and Interpretation of results
allows our method of analysis of the i/t transients.
elcccroer; stallisation transient is estimated froiu the observed
transient. Different models i.ere examined and a c^est fitting rjodcl
is derived for the i/1 variation in this taaAsient. The importance
of epecific adsorption of chloride ions in electrocrystallisation is
t&oiei from a calculation of char.-jo*transfer resistance. Our present
studies on the anodic electrocrystallisation of calomel on mercury
show that the Devanuthan aaacxni saouex iu ccrreci.
The experimental technique used in the measurement of the
i/t transient is detailed in the next Chapter* Results arc obtained
a modified electrode for txj transients for five different
concentrations of HC1 and I iC10/, namely 0.4u SCI, l.Oia IIC1, 0.1/» HC1 + 4
0.9’1 IIC10, , and x.tl4 HU10, . 4 4
In the fourth Chapter, the techniques available for stud/iny.
the kinetics of fast reactions are shown in detail. The u>asic
equation for the current due to electrochemical reactions are ^iven.
-he work done by various schools of research in this field, is
summarised in the fifth Chapter. The present state of knowledge of
the electrocr/s tallisation of calomel is discussed here.
In the next Chapter, the concepts of
electrocrystailisation and factors that govern nucleation and growth
are sum-harised. An intixxluction to the types of anodic electrocrysta—
llisation reactions are then . dven. The theories that have Lcen
developed for the stud; of electrocheaical reactions are discussed.
