GATE 2019 Syllabus for Chemical Engineering

About GATE 2019 –  In relevant branches of science, Graduate Aptitude Test in Engineering (GATE) is a national level examination, and it is conducted to offer admission into M.Tech/M.Sc in engineering/ technology/ architecture and P.hD. GATE 2019 Mock Tests have been released. It has to be mentioned that, GATE 2019 is managed by the IIT.

Two categories have been divided into each of the GATE 2019 subjects. Overall, in regards to the core subjects, the corresponding sections (of the syllabus given below) of the question paper will contain 90% of their questions and the remaining 10% on Special Topics.


About Chemical Engineering

Transforming raw materials into useful products such as clothes, food and drink, and energy is termed as Chemical Engineering. Either focusing on improving existing processes or creating new ones, Chemical engineers concentrate on methods and products – they develop and design processes to build products. Chemical Engineers are also concerned with managing resources, protecting the environment and health and safety. Since it is such a broad discipline; Chemical engineers are sometimes called ‘universal engineers’ – they are mainly concerned with transforming one thing into another.
