CHEM1201 Chemistry 2

How CHEM1201 is assessed

The offering-specific 2026 confirmed assessment controls 12/12/45/25/6. The Topic Test requires at least 45%; students must pass theory and laboratory components, complete all three tests, and attend all labs with all Smart Worksheets submitted. No numerical theory-aggregate threshold is published.

What CHEM1201 covers

Build the course in three arcs: Intermolecular Forces, Phases and Solution Formation establishes the frame, Spectroscopy and Structural Elucidation deepens it, and Crystal Fields, Colour and Magnetism tests the complete method.

It is positioned as a second-semester general chemistry course.

The course combines two early online tests with a hurdle Topic Test and an integral laboratory pass requirement.

Assessment in CHEM1201 is distributed as follows: two 12% online quizzes, a 45% Topic Test, 25% laboratory work and 6% Mastering Chemistry homework

The operational assessment conditions matter here.

The Topic Test is three hours in the examination period and requires at least 45%; the two online quizzes are not hurdles.

What makes CHEM1201 demanding is concrete: moving between molecular structure, mechanism, quantitative relationships and laboratory evidence while satisfying multiple explicit pass conditions

Students need at least 45% on the Topic Test, must pass theory and laboratory components, complete all three tests, attend every lab and submit every Smart Worksheet.

The sources do not state a numerical theory-aggregate threshold.

For enrolment planning, Chemistry 1 background is assumed; students should confirm the official requisite rules.

Key terms

Intermolecular force

Attraction or repulsion between molecules arising from charge distributions and polarisation. This chapter uses the concept when students predict phase and mixing behaviour from molecular interactions.

Phase

Physically homogeneous state of matter separated by a boundary from another state. It helps explain the reasoning required to predict phase and mixing behaviour from molecular interactions.

Solution

Homogeneous mixture in which solute species are dispersed through a solvent. Its limit matters because similarity heuristics do not replace structure, temperature and entropy.

Molarity

Amount of solute per volume of solution. This chapter uses the concept when students convert concentration units and calculate ideal vapour composition.

Molality

Amount of solute per mass of solvent. It helps explain the reasoning required to convert concentration units and calculate ideal vapour composition.

Raoult's law

Ideal-solution relation between component vapour pressure, mole fraction and pure-component vapour pressure. Its limit matters because volume can vary with temperature and non-ideal interactions break Raoult behaviour.

Colligative property

Solution property depending primarily on the number of dissolved particles under stated assumptions. This chapter uses the concept when students calculate particle-number effects and distinguish electrolyte assumptions.

Osmotic pressure

Pressure needed to prevent net solvent flow across a semipermeable membrane. It helps explain the reasoning required to calculate particle-number effects and distinguish electrolyte assumptions.

Van't Hoff factor

Effective number of dissolved particles produced per formula unit in a colligative calculation. Its limit matters because association, incomplete dissociation and concentration can make the ideal factor inaccurate.

Rate law

Empirical relationship between reaction rate and reactant concentrations. This chapter uses the concept when students infer order and rate constant from current experimental evidence.

Reaction order

Exponent describing how rate depends on a concentration in the measured law. It helps explain the reasoning required to infer order and rate constant from current experimental evidence.

Activation energy

Energy barrier parameter governing the temperature dependence of a rate constant. Its limit matters because stoichiometric coefficients do not generally reveal an empirical rate law.

Reaction mechanism

Sequence of elementary steps proposed to explain an overall reaction. This chapter uses the concept when students connect an observed rate law to a plausible step sequence and catalytic effect.

Catalyst

Species providing an alternative pathway and regenerated over the reaction cycle. It helps explain the reasoning required to connect an observed rate law to a plausible step sequence and catalytic effect.
