Chemical Kinetics

|
Purely from view point chemical kinetics is as important as the IInd Law of thermodynamics Neither humans nor any other organism could exist in air if activation energy (Eact) was not an energetic barrier to second Law because all organic compounds are thermodynamically unstable in oxygen.Action of IInd law. Without chemical kinetics there would be no life of universe Air makes life impossible unless the barrier of Eact is present.Fortunately force "The IInd law of thermodynamic is time's arrow but chemical kinetics is time's variable clock." Study of speeds of the rates o

Material Wave and Sound
|
|
1. The sound wave can also be called as elastic wave and medium is needed for their propagation. Their velocity is different for different media.2. The velocity of sound waves depends on the property of inertia and coefficient of elasticity of that medium.3. In this type of motion the energy is transferred from one point to other by the propagation of disturbance in the medium. The motion of disturbance is called the wave motion.4. In simple harmonic wave the particles of the medium execute simple harmonic motion. Each particles of the medium executes simple motion at all the times, though the phase o

YOU ARE NUTS"This kind of conversation I faced many times when I was preparing for JEE. In those days all india engineering test series were big and I am sure they are even bigger these days. Years

Rock JEE - Tips #1
|
|
Hey Friends,Years back, one day i woke up and decided that I am gonna fight for prestigious IIT JEE entrance. But didn't know how. Only coaching institutes were the only hope.

Let's see how goIIT can help you in the best possible manner.Since last few months I am writing answers to your queries. Most of the people have same questions, I had them too when I was in IIT JEE Preparation . While studying me and my best friend "Mechanicals" developed few practices which put both of us ahead of many people (we both scored good ranks in IIT). So
