WHAT IS A in chemical kinetics?
, where A is the pre-exponential factor or A-factor, Ea is the activation energy, R is the molar gas constant and T is the absolute temperature. At a given temperature, the chemical rate of a reaction depends on the value of the A-factor, the magnitude of the activation energy, and the concentrations of the reactants.
What is the purpose of kinetics?
The aim of chemical kinetics is to make predictions about the composition of reaction mixtures as a function of time, to understand the processes that occur during a reaction, and to identify what controls its rate.
What is chemical kinetics in simple words?
Chemical kinetics is the description of the rate of a chemical reaction [21]. This is the rate at which the reactants are transformed into products. This may take place by abiotic or by biological systems, such as microbial metabolism.
What do we study in kinetics?
Kinetics is the study of reaction rates and how they are affected. Many factors, such as concentration, pressure, temperature, and enzyme activity, can impact the rate of a reaction.
Why is kinetics important in chemistry?
Reaction kinetics provide a measurement of reaction rates, factors that affect the speed of a chemical reaction and insight into reaction mechanisms. Understanding the kinetics of a reaction is critical for being able to control a reaction and direct the desired outcome of the reaction.
How is kinetics used in real life?
Kinetics can be used in everyday life. When doing everyday things that require chemical reactions, such as baking, a higher temperature makes the reaction go faster.
Why is kinetics in chemistry important?
One reason for the importance of kinetics is that it provides evidence for the mechanisms of chemical processes. Besides being of intrinsic scientific interest, knowledge of reaction mechanisms is of practical use in deciding what is the most effective way of causing a reaction to occur.
What is the difference between thermodynamics and kinetics?
Thermodynamics describes the overall properties, behavior, and equilibrium composition of a system; kinetics describes the rate at which a particular process will occur and the pathway by which it will occur.
Why kinetics is important in pharmaceutical production?
It has many applications in the field of pharmaceutics including: 1. Stability and incompatibility where the rate process is generally one that leads to the inactivation of a drug through either decomposition or loss of the drug by its conversion to a less favorable physical or chemical form.
Why is thermodynamics and kinetics important?
Whereas thermodynamics tells us what can occur during a reaction process, kinetics tells us what actually occurs on an atomic or a molecular level.
