Teachers and students! “Insight Model Papers for First Year Chemistry, Chapter 8” are present before you. As the chapter name “Chemical Equilibrium” indicates, it is about reversible reactions, the reactions that proceed in both forward and reverse directions. Related topics like Law of mass action, equilibrium constant and its applications, Le-Chatelier’s principle, synthesis of ammonia by Haber’s process, synthesis of sulphur trioxide by contact process, ionization constant of water, pH & pOH, dissociation constant of acids and bases, Lowery-Bronsted acid base concept, common ion effect, buffer & buffer capacity, and solubility product, all are discussed in detail here. These concepts are further clarified with the help of numerical examples given along with each article. Theory articles & examples, exercise MCQs & numericals, all are included in these model papers.

From examination point of view, this chapter is very important and is also favourite to most of the teachers and students. This is because most often one numerical question is included from this chapter into the board papers. Attempting a numerical is somewhat easier as compared to the theory question so it is considered a blessing for the students. The students are, therefore, advised to include this chapter preferably into their preparation manual.

The marks weightage of this chapter is of 10 marks; 2 MCQs for 2 marks, two short questions for 4 marks and one long question or numerical for 4 marks. The long question of this chapter is paired with that of chapter 11 in Q. No. 8 of the subjective portion. Two short questions from this chapter are grouped with those of chapters 4,5 & 11 in Q. No. 3 of the subjective portion.

  • Half chapter tests
  • Complete chapter tests (regular syllabus)
  • Complete chapter tests (smart syllabus)

The detail of each category is given at their respective places.

C. Smart Syllabus Tests

These are complete chapter tests arranged according to smart syllabus. ‘Smart Syllabus Tests’ have about 40% short syllabus due to Covid-19 Pandemic. In smart syllabus, some topics from the chapter are omitted. For example, in chaptr 8, topic number 8.6 & 8.9 are excluded, while the remaining topics are the part of the smart syllabus.
