## NCERT Solutions for Class 12 Chemistry Chapter 4 Chemical kinetics

Chemical kinetics deals with the average and instantaneous rate of reaction,  factors affecting these and the mechanism of the reaction. Chemical kinetics helps students to understand how chemical reactions occur.  This chapter holds 5 marks in the class 12 CBSE board exam of chemistry. In this chapter, there are 30 questions in the exercise and 9 intext questions. To clear students doubts the NCERT Solutions for Class 12 Chemistry Chapter 4 Chemical kinetics are prepared and designed by subject experts. This chapter is important for both CBSE Board exam as well as competitive exams like JEE Mains, VITEEE, BITSAT, etc. so, students must pay special attention to this chapter.

In NCERT Class 12 Chemistry Chapter 4 Chemical kinetics there are total six topics, which basically deals with the average and instantaneous rate of a reaction, factors affecting the rate of reaction, the integrated rate equations for the zero and first order reaction, etc. After completing the Class 12 Chemistry Chapter 4 Chemical kinetics students will be able to distinguish between elementary reactions and complex reactions, define rate constant and describe collision theory and also able to differentiate between the molecularity and order of a reaction.

Rate of reaction- It is defined as the rate of change in concentration of reactant or product. Unit of rate is $mole\:L^{-1}S^{-1}$.

Reactants, R  $\rightarrow$ Products, P

nA+mB  $\rightarrow$ pC+qD

$Rate=-\frac{1}{n}\frac{\Delta \left [ A \right ]}{\Delta t}=-\frac{1}{m}\frac{\Delta \left [ B \right ]}{\Delta t}=+\frac{1}{p}\frac{\Delta \left [ C \right ]}{\Delta t}=+\frac{1}{n}\frac{\Delta \left [ D \right ]}{\Delta t}$
