The decomposition of tris-(oxalato)-manganate (III) complex ion as the reaction suitable for the laboratory practice on chemical kinetics
Abstract: The complex ion [Mn(C2O4)3]3- is very photosensitive and rapidly decomposes at the daylight even at ambient temperatures. Although the mechanism of this reaction is complicated, its kinetic equation obeys the pseudo-first order. In addition, the tris-(oxalate)-manganate ion has a low thermal stability, and the reaction of its decomposition is highly affected by temperature. This makes this reaction very suitable for demonstrating the laws of chemical kinetics to the students – …

Kinetics and Mechanisms of the Reduction of Some Carbonyl Compounds with Sodium Dithionite in Aqueous Alkaline Medium
Abstract: Kinetics of the reduction of some carbonyl compounds (acetophenone, benzophenone, benzaldehyde, and salicylaldehyde) with sodium dithionite was studied at 28± 0.5oC and basic concentration in the range of 0.01 to 0.05 mol dm-3 (NaHCO3). Under these conditions, the reaction rates were found to be first order with respect to sodium dithionite as plot of log kobs versus log [S2O42-] showed linearity to about 95% extent of reaction, however, the overall …

Kinetic and Mechanistic Study of Oxidation of Benzydamine Hydrochloride by Permanganate (VII) in Acidic Medium
Abstract: The kinetics and mechanism of Permanganate (Mn (VII)) oxidation of Benzydamine hydrochloride (B.HCl) in acidic medium has been studied at 26 ± 0.1°C. The reaction shows first order dependence in [Mn (VII)], less than unit order in [B.HCl] and fractional order dependence in [H2SO4]. Variation of ionic strength by the addition of KCl has no significant effect on the rate. The stoichiometry of the reaction is found to be 1:4 …

A Note on-Thermodynamics in Our Daily Life
Abstract: Thermodynamics plays crucial role in our day-to-day life. Almost all the activities that we do or observe are all based on the principles of thermodynamics. Here, some of the common routine activities are brought into limelight that is explained by the phenomenon of thermodynamics. Keywords: energy, entropy, heat transfer, thermodynamics

Chemical composition in Atmosphere: An Introductory Approach for Students
Abstract: Our atmosphere is divided into different strata above the earth’s surface. The region closest to earth’s surface is the troposphere that is extended upto 10-16 km above the surface. This layer or strata is followed by stratosphere which extends upto nearly 50 km. Above it is the mesosphere region, which covers about 50-85 km from surface of the earth. Beyond the mesosphere lies the thermosphere which goes from 85-500 km …
