APPLIED CHEMISTRY BE04005051 2026 From 01-01-2026 to 06-05-2026

Dear Students,

Welcome to Semester IV of the Chemical Engineering program at Government Engineering College, Valsad. I am pleased to welcome you to the course Applied Chemistry (Subject Code: BE04005051), a basic science course that plays a crucial role in building strong chemical fundamentals required for core engineering subjects.

Applied Chemistry bridges the gap between fundamental chemical principles and their engineering applications. In this course, you will explore molecular structure, organic reaction mechanisms, stereochemistry, phase rule, chemical kinetics, thermochemistry, catalysis, and modern analytical techniques. These concepts are essential for understanding real-world chemical processes encountered in industry and research.

The course is designed not only to strengthen your conceptual clarity, but also to enhance your analytical thinking, problem-solving ability, and experimental skills through laboratory work, assignments, problem-based learning (PBL), and self-learning activities.

Throughout the semester, students are encouraged to:

Actively participate in lectures and discussions
Maintain discipline and safety in the laboratory
Develop curiosity beyond the syllabus
Connect theory with practical and industrial applications

All important lecture notes, laboratory instructions, assignments, announcements, and learning resources will be shared through this blog from time to time. Students are advised to visit this page regularly.

I look forward to an engaging, disciplined, and productive learning journey with all of you. Let us work together to make this semester meaningful and academically enriching.

With best wishes for the semester ahead.
