Equilibrium is a high-weightage chapter for the NEET examination. Here we are sharing an article comprising NEET video lectures, Summary Notes, and Previous year questions with details solutions of the topic Equilibrium.
In a chemical reaction, equilibrium is defined as the state at which there is no further change in concentrations of reactants and products. For example, At equilibrium, the rate of forward reaction is equal to the rate of backward reaction.
There are three types of Physical Equilibruim
- Solid-liquid Equilibrium
- Liquid-Vapour Equilibrium
- Solid – Vapour Equilibrium
Characteristics of Equilibruim involving Physical Process
- Only closed systems can achieve equilibrium at a given temperature.
- At stable conditions, the system is dynamic if both opposing processes occur at the same rate.
- All measurable properties in a system remain constant.
- Equilibrium is defined as the constant value of one of its parameters, which is then attained for a physical process.
Chemical reactions can occur in both forward and reverse directions. When the rate of forward reaction equals the rate of backward reaction, the chemical equilibrium is dynamic.
Reversible Reaction – Reversible reactions are those that do not always complete and can be made to proceed in the opposite direction under certain conditions.
Irreversible Reactions – Irreversible reactions are those that always complete in one direction.
Characteristics of Chemical Equilibruim
- Equilibrium is possible from either side.
- Equilibrium is dynamic in nature, which means that at equilibrium, the reaction does not stop.
- There is no change in the concentration of various species when they are in equilibrium.
- The presence of a catalyst has no effect on the equilibrium state. Catalyst aids in the rapid attainment of equilibrium.
- It is possible in a closed container.
- The process’s observable properties become constant and remain unchanged.
The first video session is conducted by Mr Yogesh Kumar. He is a subject matter expert and a NEET coach. He will discuss the topic Equilibruim in a single shot.
The next four sessions are from Mr Umar Arif. He is a subject matter expert in NEET Chemistry. He discusses the topic Equilibruim deeply through these four video sessions.
Basidia’s NEET special daily live classes for various subjects will be conducted 4 to 5 times a day with the vision of equipping you with the right knowledge to crack the NEET exam. The sessions are conducted live and the same will be uploaded as a video on the YouTube channel.
