If you go around asking students about their favorite part of chemistry, we can assure you that most of them would end up answering ‘physical chemistry’. The amalgamation of the concepts of maths, physics, and chemistry makes for this to be a very exciting and fun subject. It is important from the exam point of view as well, since, for instance, around 40% of chemistry questions in JEE exam 2022 are from physical chemistry. Therefore, if you can get all of them right, you can score 48 marks from just physical chemistry!
Physical chemistry isn’t about memorizing exceptions or learning by heart like inorganic or organic chemistry sometimes can be. It is all about understanding the concepts, and applying them to questions with the help of a bit of physics here and a tinge of mathematics there. It is undoubtedly the most fun part of chemistry, and students enjoy practicing physical chemistry very much for JEE 2022.
How to prepare physical chemistry for JEE 2022?
Given the importance of this subject in JEE syllabus, it is obvious to take great care in the preparation. Following certain tips and tricks to help score extra marks in this subject comes as a blessing for students. Here are some of those tips-
1. The constants are important. Remember them.
Mathematical and chemical constants like the Avogadro number, Planck’s constant, and the universal gas constant are crucial to getting those physical chemistry questions and equations right. Remembering the values of these constants up to at least three decimal places should do the trick. Also, for ease of calculation, remembering close approximations to these constants can be of great help for students. This can drastically decrease the time taken to solve a question, thereby leaving more time to attempt the difficult ones.
2. Equilibrium is an important part of physical chemistry
Especially from a competitive point of view, chemical and ionic equilibrium are two of the most important parts of physical chemistry. These topics prove to be challenging for students; hence it is important to understand each and every step. What’s more, is that these concepts find their way into different topics of physical chemistry down the road, therefore, it makes sense to be thorough with both chemical and ionic equilibrium concepts.
3. Practice makes you perfect
The biggest key to acing physical chemistry is undoubtedly practice. Solve as many JEE mock tests as you can and then judge your performances critically. Practice with JEE Test & Discussion Course by Aakash will decrease the time taken to solve a question, and will increase the understanding of problem-solving techniques in physical chemistry. Enough practice almost makes you mechanical, to the point where you see a question and your hands know automatically what to do in order to arrive at a solution.
Physical chemistry, one of the most fun and scoring parts of chemistry, is one that needs a lot of practice. What are you waiting for? Grab a book, a register, and a pen, and get started!
