What is difference between rate of …

YA.. i just said thanks and reported.. god knows who thought what..? we need to get used to this cbse..

Who reported this... i didnt say something wrong.?

No need

Difference between rate of reaction and reaction rate constant are as follows: RATE OF REACTION REACTION RATE CONSTANT Rate of reaction is the change in concentration of a reactant or product per unit time. It is a constant of proportionality in the rate law equation and is equal to the rate of reaction when the molar concentration of each of the reaction is unity. The rate of reaction at any instant of time depends upon the molar concentrations of the reactants at that time. The rate constant is constant for a particular reaction at a particular temperature and does not depend upon the concentrations of the reactants. Its units are always moles litre It units depend upon the order or reaction. A reaction is said to be of the zero order, first order, second order, and third order if some of concentration terms is equal to 0, 1, 2 and 3 respectively
