Determination of rate of reaction

The rate of reaction at any time t is determined in the following way :

(i) Concentration of any of the reactants or products which ever may be convenient is determined at various time intervals.

(ii) Then concentration vs time curve is drawn.

(iii) A tangent is drawn at the point p of the curve which corresponds to the time t at which rate is to be determined.

(iv) The slope of the tangent gives the rate of reaction at the required time as shown below.

(CR and CP denote concentration of reactant and product respectively)

Unit of rate $\large \frac{Unit \; of \; Concentration}{unit \; of \; time} $ = Concentration time−1 i.e. mole L−1 S−1
