MCH 013 subject name and where it sits in IGNOU MSCCHEM

MCH 013 General Physical Chemistry is a 4-credit theory course. It is listed in the course table of the IGNOU Master of Science (Chemistry) (MSCCHEM) programme. This course is placed in the First Year (First Semester) within the School of Sciences (SOS), with English as the programme medium. A 4-credit course requires 120 hours of learner study, as one IGNOU credit equals 30 hours of study.

In the same MSCCHEM term, learners study several other courses. These include MCH 011 Inorganic Chemistry – I (4 credits), MCH 012 Organic Chemistry – I (4 credits), MCH 014 Mathematics for Chemists (2 credits), and MCH 015 Biology for Chemists (2 credits). The term also includes three lab courses: MCHL 011 Chemistry Lab -I (2 credits), MCHL 012 Chemistry Lab -II (2 credits), and MCHL 013 Chemistry Lab -II (2 credits).
