might say it as organization full of opportunities but for me‚ it is a “CATALYST”. Like in chemistry the catalyst is a substance which fastens the reaction without taking part in the reaction. PDRC is an organization that catalyses students especially from the marginalized group by proper guidelines and facilities. My journey with PDRC began in 2010 A.D‚ it was then when I first came to PDRC with my father in search of the catalyst. I grew up with dream to become a doctor. I was science student in

Esterification reaction dose not required catalyst. We add some additives like NaAc = Max PPM ‚ OPA = Max PPM ‚ Penta- Erythritol = Max PPM. These additives increases the performance of Polymer Polycondensation reaction is carried out under vacuum and high temperature in the range of 292 to 300 deg C. This reaction is carried out with the help of catalyst. EG is evolved in the reaction. Which we collect as crude EG and distilled off further recycling. The catalyst used in the process is Sb2O3 =

chlorine bleaches. Now bleach - in scientific terms - is a kind of catalyst. A catalyst is a chemical that increases the reaction rate of a chemical reaction (catalyse)‚ and the chemical reaction involves enzymes. So to understand how bleach works‚ we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives‚ it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with

O2(g))‚ but that would take too long. This reaction can be sped up with various methods such as modifying the temperature‚ modifying the concentration‚ or introducing a catalyst. We will be specifically looking at the effect of concentration of the H2O2 solution rather than the effect of the temperature. We will also introduce a catalyst‚ Manganese(IV) Oxide (MnO2)‚ in order to speed up the reaction so that it can occur‚ however it will be controlled so that we only look at the effect of concentration

OZONE LAYER The Earth ’s ozone layer protects all life from the sun ’s harmful radiation‚ but human activities have damaged this shield. Less protection from ultraviolet light will‚ over time‚ lead to higher skin cancer and cataract rates and crop damage. The ozone layer is one layer of the stratosphere‚ the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. Ozone is only a trace gas in the atmosphere only about 3 molecules for every

The redox reaction is depicted as: [BH4] - + 8[Fe (CN) 6] -3 + 3H2O H2BO3 - + 8[Fe (CN) 6] -4+ 8H+ The reaction can even proceed without a catalyst‚ but it has been reported that it is a slow reaction‚ which follows zero-order kinetics. The progress of the reduction reaction of Potassium hexacyanoferrate (III) to Potassium hexacyanoferrate (II) was monitored through changes in the UV-visible

The time before the reaction proceeded was recorded and calculations were done to obtain necessary information. It was identified that increasing the reactant concentration would increase the rate of reaction. Likewise‚ higher temperature increased the rate. Finally‚ the presence of catalyst had enormous effect on the reaction rate. It increased as the catalyst was added. Based on the results obtained‚ it
