Question

Physical chemistry is the branch of chemistry which deals with the study of:
A.Physical aspects of chemical reactions
B.Qualitative and quantitative analysis of chemical substances
C.Interaction of light with chemical substances
D.None of these

Answer 1

We have to know that chemistry is the study of atomic matter that is made up of chemical elements particularly its chemical reactions, yet in addition including its properties, structure, arrangement, conduct, and changes as they identify with the compound reactions. Chemistry is dominantly concerned about molecules and their cooperation with different atoms, and especially with the properties of bonds.

Complete answer:
We have to know that Physical chemistry – investigation of the physical and crucial premise of substance frameworks and cycles. Specifically, the energetics and elements of such frameworks and cycles are important to actual scientists. Significant portions of study comprises synthetic thermodynamics, chemical kinetics, electrochemistry, statistical mechanics, spectroscopy, and all the more as of late, astrochemistry. Physical science has enormous coverage with atomic physical science. Physical chemistry includes the utilization of little math in inferring conditions. It is normally connected with quantum science and hypothetical science. Physical chemistry is an unmistakable order from physical science, however once more, there is solid cover.
Some of the major areas of physical chemistry include chemical kinetics, electrochemistry, femtochemistry, quantum chemistry, surface science, spectroscopy, photochemistry, thermochemistry, stereochemistry, solid-state chemistry.
We can say that physical chemistry is a field of chemistry that deals with the study of physical aspects of chemical reactions.

Option (A) is correct.

Note:
We have to know that other branches of chemistry include organic chemistry and inorganic chemistry. We can say that organic chemistry is a field of chemistry that deals with study of structure, properties, and mechanisms of organic compounds. Any compound that exhibits a skeleton of carbon is known as an organic compound. We can say that inorganic chemistry is the branch of chemistry which deals with reactions and properties of inorganic compounds.
