Hello dear,

Chemical kinetics is the toughest for some people and also the easiest chapters in Chemistry class 12th. I think some concepts are not clear to you that's why you are lagging in this chapter. Understand the concepts clearly the reactions: first order, second order and third order. Most questions come from this part and also some half life-related questions.

You should read and revise the whole chapter once again or you can follow PHYSICS WALLAH for chemical kinetics. I am sure you will understand it more precisely.

Hope you understand. Revert for any query.

Good luck:)
