Introduction to the chemical process

A chemical process is a process which involves chemical reactions to yield a new product from raw materials. Such a chemical process can occur by reacting with external reagents or by itself. This process results in the change in the composition of materials or chemicals used. The chemical process is generally used in manufacturing new products with the help of chemical reactions on an industrial scale. In general, in the chemical industry, a chemical process is used in between the physical process (do not involve chemical reactions). Chemical processes application is used in oil refining and other refineries, polymer and pharmaceutical manufacturing, natural gas processing, food processing, and water and wastewater treatment.

In chemical engineering, a chemical process is also known as unit process. It consists of a various unit process like hydrogenation, dehydrogenation, oxidation, reduction, hydration, dehydration, hydrolysis, catalysis, alkylation, dealkylation, polymerisation, esterification etc. The responsibility of a chemical engineer in an industry is to take the basic chemical reactions worked out in the laboratory by the chemists and to apply them to the industry.

Heat effects of chemical or physical processes can be measured in a calorimeter.

Can someone please paraphrase this to me.... if possible. Heat effects of chemical or physical processes can be measured in a calorimeter. Instruments of widely varying designs are employed to accommodate the large range of experimental conditions encountered. For instance, the heat effects to be measured may range from milliJoules to milliliter, quantities involved from fractions of milliliters to hundreds of milliliters and from milligrams to grams, operating temperatures from below liquid helium temperature (4.2 K) to 2000o C, and...

When conducting chemical reactions in the lab or in industrial processes, it can be important to know whether a reaction has reached equilibrium. By measuring the reaction quotient, Q, of a chemical reaction and comparing it to the equilibrium constant, K, we can identify whether a reaction is at equilibrium. For the reaction aA+bB⇌cC+dD the reaction quotient, Q, is given by the expression Q=[C]c[D]d[A]a[B]b under any conditions. The value of Q is equal to K only at equilibrium. Part B...

1) why is the change in the enthalpy a meaningful quantity for many chemical processes? 2) Enthalpy is said to be a state function. What is it about state functions that makes them particularly useful? 3) During a constant pressure process the system absorbs heat from the surrounding. Does the enthalpy of the system increase or decrease during the process?

Background Information: In the nervous system, the brain processes information by transmission of electrical and chemical signals through a network of neurons. These signals travel through synapses which connect two neurons. Neuroligins are cell-adhesion molecules that function to connect two neurons at synapses and mediate proper signalling across the synapse. Interestingly, neuroligin function has been linked to autism spectrum disorder (ASD) which is primarily manifested by delayed development and deficiency in social interaction and communication in patients. Mutations in genes...
