Concentration dependence of rate is a differential equation (equation 8). It is tedious to determine the instantaneous rates from the slopes of the tangents for each value of t and this in turn makes the rate law determination difficult. To avoid this difficulty, the integrated form of th..

Calculation of Degree of Dissociation - Degree of Dissociation [ a ] - It is defined as the fraction of the total number of molecules undergoing dissociation at a given concentration. Example: If 100 molecules of acetic acid are added to H 2 O of which 10 molecules ionise, then or 1) If 0..

It is defined as the fraction of the total number of molecules undergoing dissociation at a given concentration. Example: If 100 molecules of acetic acid are added to H 2 O of which 10 molecules ionise, then or 1) If 0.1M acetic acid has 25% degree of dissociation, what is the concentration of H 2 ..

For a zero order reaction, the rate is independent of concentration of the reactant. For e.g., A Products Integration of the equation gives At t = 0, [A] = [A] o = constant Therefore equation becomes A plot of [A], that is concentration, versus time t, will be linear ..
