Lechatelier's Principle : Imagine there are 2 room (A and B) connected with each other and 100 students sitting in each room . Since both rooms are connected equal number of students (say 10) move from one room to another in a given time interval without affecting total number of students in each room . We say it as equilibrium . Why? Because movement (reaction ) occurs in both direction without affecting the strength (Concentration) of each room . If any external stress is induced in any room the net flow of number student from one room to another will change , and we say equilibrium will get disturbed . This is natural , system fights back to counter external force . Similar situation arise if any reversible reaction which is at equilibrium faces any external force . Rate of forward and backward reaction does not remain equal on application of external force (means equilibrium gets disturbed). We can relate it with concept of Reaction Quotient(Q) . At equilibr...
One frequently asked questions by JEE or NEET students is “how many hours should I study to crack the exam?” Is my study hours sufficient? Is my preparation going well? Often, they compare their sitting hour with their friend which lead to unnecessary pressure and competition among students. We will answer these questions in this article . There is no any fixed number of hours that guarantee success in JEE or NEET exam. What matters more is how many productive hours of study you are doing without disturbing your mental health. Some students may study fewer hours but achieve better results because their study time is focused and well planned. Here are some points that I would suggest students consider: 1) Understand your preparation level: A student with stronger basics may need less time to understand the topic than someone whose fundamentals are still developing. Similarly, A school going student has less number of hours for self study than one not a...
Welcome to Lessons Beyond Class! Having been Chemistry mentor for more than a decade, I always felt that there are certain nuances of preparation and students life that deserve to be shared beyond the classroom. Everyday, when I enter a classroom and interact with students, I observe not only their academic problems but also their curiosity, doubts, struggles and aspirations. Many of these issues can be addressed in class, but lmited classroom time does not allow us to discuss everything in classroom. To address some of these concerns, I decided to bring my experiences and observations to a common plateform. Lessons Beyond Classroom is an effort to address the doubts and dilemmas that students face during their preparation and everyday life. These may be academic doubts related to chemistry, JEE and NEET , or emotional and practical challenges that students often experience during their journey. Every student is unique, and so are their challenges . Some students need more ...
