Chemical thermodynamics and Chemical Kinetics are both different but related as they are involved in the study of reactions and the factors variations.

Here's it from my notes.

Chemical Kinetics v.s. Chemical Thermodynamics

  1. In C.K we are more concerned with the rate of reactions. It tells us how fast or slow a reaction is proceeding, but in thermodynamics we are majorly concerned with the heat change (whether a reaction is endo or exothermic)
  2. In C.K. we are also concerned with instantaneous rate of reaction ( the rate of reaction at a particular moment) while in C.T we only take the whole reaction regardless of the time taken to complete it.
  3. C.K. is studied with special reference to the steps of the reaction ( like in determining the order of reaction) while in C.T. we are concerned only with the whole reaction, it doesn't matter how many steps it took 1 or 5 or many (see Hess's law).

What is the difference between dynamics and kinetics in the context of chemical reactions?

In the context of chemical reactions, dynamics refers to the study of the speed and pathways of reactions, while kinetics focuses on the factors that influence the rate of a reaction. Dynamics looks at how molecules move and interact during a reaction, while kinetics examines the factors that affect how quickly a reaction occurs.


What is the relationship between kinetics and equilibrium in chemical reactions?

In chemical reactions, kinetics refers to the speed at which a reaction occurs, while equilibrium is the point where the rates of the forward and reverse reactions are equal. Kinetics determines how quickly a reaction reaches equilibrium, and equilibrium represents a balance between the forward and reverse reactions.


What is the relationship between the Joule temperature and the energy transfer in a thermodynamic system?

The Joule temperature is a measure of how the energy of a thermodynamic system changes with temperature. It quantifies the relationship between temperature and energy transfer in the system.


What is the fundamental interval on the thermodynamics scale?

The fundamental interval on the thermodynamic scale is the Kelvin scale, where the interval between each degree is the same size. This scale begins at absolute zero and is used to measure temperature in thermodynamics.


What is the relationship between the work done on a system and the work done by a system in a thermodynamic process?

In a thermodynamic process, the work done on a system is equal and opposite to the work done by the system. This is known as the principle of conservation of energy.

What is the difference between a thermodynamic product and a kinetic product in a chemical reaction?

In a chemical reaction, a thermodynamic product is the most stable product formed at the end of the reaction, while a kinetic product is formed faster but may not be as stable as the thermodynamic product in the long run.


What is the difference between thermodynamic and kinetic stability in chemical reactions?

Thermodynamic stability refers to the overall energy difference between reactants and products in a chemical reaction, while kinetic stability refers to the rate at which a reaction occurs. Thermodynamic stability is determined by the final energy state of the reaction, while kinetic stability is influenced by factors such as temperature, pressure, and catalysts that affect the reaction rate.


What is the difference between the kinetic and thermodynamic product in a chemical reaction?

In a chemical reaction, the kinetic product is formed faster and is usually less stable, while the thermodynamic product is formed more slowly but is more stable in the long run.


What is the difference between the kinetic and thermodynamic products in a chemical reaction?

In a chemical reaction, the kinetic product is formed faster and is usually less stable, while the thermodynamic product is formed more slowly but is more stable in the long run.


What is the difference between the thermodynamic and kinetic products in a chemical reaction?

In a chemical reaction, the thermodynamic product is the most stable product formed under specific conditions, while the kinetic product is the product formed faster but may not be the most stable.


How can one determine the difference between kinetic and thermodynamic products in a chemical reaction?

In a chemical reaction, the difference between kinetic and thermodynamic products can be determined by analyzing the reaction conditions. Kinetic products are formed at lower temperatures and shorter reaction times, while thermodynamic products are favored at higher temperatures and longer reaction times. Kinetic products are typically formed faster and are less stable, while thermodynamic products are more stable and favored in equilibrium conditions.

What is the difference between Chemical kinetics vs Chemical decay?

Chemical decay, also known as radioactive decay, is a process that occurs naturally (usually in isotopes or unstable substances) Chemical Kinetics is one of the ways you can analyze radioactive decay. Although it should be noted that radioactive decay undergoes first order decay when using Chemical Kinetics.
