Zero Order ReactionA reaction is of zero order when the rate of reaction is independent of the concentration of materials. The rate of reaction is a constant. When the limiting reactant is completely consumed, the reaction stops abruptly. The zero order rate law for the general reaction is written as the equation which on integration of both sides gives When t = 0 the concentration of A is [A]0. The constant of integration must be [A]0. Now the integrated form of zero-order kinetics can be written as follows Plotting [A] versus t will give a straight line with slope -k. First Order ReactionA general unimolecular reaction where A is

So here I will be clearing some misconceptions that students generally make while studying Chemical Kinetics. But it is not totally their fault as they are taught that way.FIRST MISCONCEPTION----------------------------------------OK.......So tell me how do you define rate in chemical kinetics.....????Students normally answer rate of a reaction as rate of change of CONCENTRATION with respect to TIME.... That is........... Rate = d(C)/dtNow this definition in one's mind actually has no basic meaning and also this is TOTALLY WRONG conception. First let me tell you why it has no meaning and then i will tell why it is wrong.While mentioning the rate one must mention wh
