Interpretation Introduction

Interpretation:

The rate laws should be determined according to initial rates of a reaction.

Concept Introduction: Let’s assume a simple reaction in which there is only one reactant ’A”. The rate law for such a reaction will be given by rate constant (k) times concentration of ’A’ raised to some power say ’n”.

i.e. ${\text{dx/dt = k[A]}}^{\text{n}}$

The order of reaction ’n’ is usually an integer between 0 and 2. So, by changing the concentration of reactant [A] and then observing the initial rate ${\left(\text{dx}/\text{dt}\right)}_{\text{initial}}$, we can deduce the value of ’n”.
