Summary

• Description:

  The PDF document comprises STAREHE GIRLS' CENTRE Chemistry Paper 2 Pre Mock Exam with Answers (Marking Scheme). The marking scheme is in a different document.

  It was a Pre-mock Chemistry Paper 2 (Theory) examination.

  This examination evaluates advanced theoretical problem-solving in inorganic reaction pathways, industrial chemical manufacturing, thermochemistry, reaction kinetics, and electrochemistry. It is structured to mirror national exam standards and rigorous analytical assessments.

  • Duration: 2 Hours
  • Total Marks: 80
  • Number of Questions: 7 (Questions 1 - 7)
  • Structure: A single continuous paper of 7 compulsory multi-part extended structured questions totaling 80 marks.

  It covers the following topics:

  • Section A:
    • Periodic table trends, electronic configurations, bonding structures, and separation of sulphate mixtures
    • Thermochemistry and reaction kinetics (Hess's Law calculations, decomposition of hydrogen peroxide, and graphical reaction rate determination)
    • Hydrocarbon chemistry (laboratory preparation of ethyne, addition halogenation, PVC polymerization, esterification, and fuel heating values)
    • Extractive metallurgy of zinc (froth flotation, roasting, smelting, and electrochemical reduction)
    • Industrial gas isolation (fractional distillation of liquid air, Ostwald process, Haber process, and ammonium sulphate production calculations)
    • Large-scale industrial manufacture of sodium carbonate (Solvay process flow chart, recycling of by-products, and concentrated sulfuric acid reactions)
    • Preparation and chemical properties of hydrogen gas (reducing action on copper (II) oxide and industrial hydrogenation)
