Branches and Topics in Physical Chemistry
Physical chemistry is a part of chemistry. But the field of physical chemistry includes many branches within it. Each of these branches of physical chemistry finds application in our daily life. They offer exciting insight into how this field of science serves us.
Identification of Elements
Energy striking atoms can make its electrons jump from one energy level to a higher one. The energy that they absorb is different for each element, kind of like a fingerprint, which can be used to identify the elements contained in a substance.
Heat Transfer
In chemical reactions, heat can be transferred into a substance or out of it. Thermochemistry tells us whether a reaction gives off heat like the burning of wood or whether it absorbs heat like chemical cold packs used for an injury. When a reaction creates heat, it is called exothermic, and when the reaction absorbs heat, it is endothermic.
How Fast a Reaction Occurs
The area of kinetics deals with the rates of reactions. They can occur in femtoseconds (0.000000000000001 seconds) or over millions of years. To find out the rate of a reaction, we use the rate constant for the reaction.
Electrochemistry
One practical use of electrochemistry is plating, where an expensive metal can be plated onto another less expensive metal. Metals can also be electroplated decoratively onto plastic or glass. Batteries use electrochemical processes to break bonds and release contained energy as electricity.
