Important Topics for NEET
Yes, there are specific topics in physical chemistry that you should focus on for NEET. Here are some of the most critical issues:
- Basic Concepts: This is the fundamental part of chemistry; understanding these concepts is crucial for understanding physical chemistry. The mole concept helps calculate the amount of a substance in a chemical reaction. Stoichiometry helps in determining the amount of reactants and products in a response. Atomic structure helps in understanding the electronic configuration of atoms. Chemical bonding helps in understanding how particles are held together in molecules. The periodic table helps in understanding the properties of elements.
- Thermodynamics: This topic deals with studying energy changes during chemical reactions. The first law of thermodynamics states that energy cannot be created or destroyed but can only be converted from one form to another. Heat capacity is the amount of heat energy required to raise the temperature of a substance by 1 degree Celsius. Enthalpy is the heat content of a sense at constant pressure. Thermodynamic processes include isothermal, isobaric, isochoric, and adiabatic processes. The second law of thermodynamics states that the universe’s entropy always increases.
- Chemical Equilibrium: This topic deals with the state of balance in chemical reactions. The law of mass action states that the rate of a chemical reaction is proportional to the product of the concentrations of the reactants raised to their stoichiometric coefficients. The equilibrium constant is the ratio of the effect of the attention of the products to the development of the attention of the reactants. Le Chatelier’s principle states that any change in the conditions of a system at equilibrium will cause the system to readjust to a new equilibrium state. Acid-base balance deals with the behaviour of acids and bases in a solution.
- Chemical Kinetics: This topic deals with the rate of chemical reactions. The reaction rate is the change in concentration of a reactant or product over time. The order response is the sum of the exponents in the rate law equation. The rate constant is the proportionality constant in the rate law equation. Activation energy is the energy required for a reaction to occur.
- Electrochemistry: This topic deals with studying chemical reactions involving electron transfer. Electrolytic cells use electrical energy to drive a non-spontaneous response. Galvanic cells use a spontaneous reaction to generate electrical power. The Nernst equation relates the cell potential to the concentrations of the reactants and products. Faraday’s laws of electrolysis relate the amount of substance deposited or liberated at an electrode to the current passing through the cell.
- Solutions: This topic deals with the properties of solutions. Colligative properties depend on the number of particles in a solution rather than the type of particles. Ideal solutions follow Raoult’s law, which states that the vapour pressure of a solution is proportional to the mole fraction of the solvent in the solution. Non-ideal solutions deviate from Raoult’s law. Osmosis is the movement of solvent molecules across a semipermeable membrane from a lower solute concentration region to a higher solute concentration region.
- Surface Chemistry: This topic deals with the study of the surface properties of substances. Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. Colloids are particles that are intermediate in size between molecules and bulk solids. Emulsions are colloidal suspensions of two immiscible liquids.
