Hi Pratik,

The work of a chemical engineer is to help in the advancement of systems that depend upon material response for their functioning. They also know how to predict and tailor the outcomes of chemical reactions and synthesise chemicals.

They deal with design, development of processes and operation of machines and plants through which the physical or chemical state of materials undergo various changes.
