Physical Chemistry is all about
WHY 🤨 a certain reaction takes place
HOW 🧐 do the reaction conditions affect the products of a reaction
HOW MUCH 🤕 of the reactant is required and how much product will be formed.
WHEN 👀 does a reaction proceed to completion and when it does not.
WHAT are the various types of substances and why do they behave in the way they do.
Click on the links below to select what you want to learn today. You don't need to and you SHOULD NOT do the full topic in a day else the 'fun' element in the whole process of learning disappears. So keep a pen and paper handy to take down the notes and also practice questions when asked to.
Remember- Regularity is the key to better learning and understanding.☺️
Solute, solvent and solution
Types of solution-:
Saturated/unsaturated/super saturated
Ideal and non ideal solution
Raoult's law
Solutions with positive deviation form Raoult's law ( azeotropic mixtures and their separation)
Solutions with negative deviation from Raoult's law (Azeotropic mixtures and their separation)
What is mole and how does it relate to:
Number of particles ( atoms, molecules and ions)
Volume of gas
Mass of the substance
What is chemical bonding
What are the various types of chemical bonding.
