GTLE Subject Specialism Chemistry study guide
GTLE Subject Specialism Chemistry · Work through your exam, one topic at a time.
The GTLE Subject Specialism Chemistry paper is the chemistry-specific component of Ghana's teacher licensure examination route for candidates who intend to teach chemistry in basic or secondary schools. It is aimed at graduate and trainee teachers whose degree includes chemistry or a closely related science, and it tests whether they can handle the subject at the depth required to teach it confidently and accurately, not merely whether they can recall a syllabus. The GTLE Subject Specialism Chemistry study guide has 11 sections and about 4,580 words.
01Atomic Structure and Periodicity
Atomic structure questions on this paper pair quantum-number bookkeeping with the periodic trends that follow from effective nuclear charge (Z eff). You should be able to write configurations for atoms and ions, justify anomalous ionisation energies, and rank species by radius, ionisation energy or electronegativity.
467 words, about 2 min02Chemical Bonding and Intermolecular Forces
Bonding questions test whether you can move from a Lewis structure to a three-dimensional shape, decide polarity, then use intermolecular forces to explain a physical property. Molecular orbital theory appears mainly for diatomics and bond order.
418 words, about 2 min03Stoichiometry and Chemical Calculations
Stoichiometry marks are lost on units and on deciding which reagent runs out, not on arithmetic. The paper expects moles from mass, concentration or gas volume, correct limiting-reagent logic, titration and dilution calculations, and sensible significant figures.
408 words, about 2 min04States of Matter and Kinetic Theory
Gas-law and solid-state questions test the ideal model, its limits, and the link between microscopic motion and measurable properties. Expect the ideal gas equation, partial pressures, effusion, real-gas deviations and unit-cell densities.
443 words, about 2 min05Thermodynamics and Thermochemistry
Thermodynamics questions ask you to track energy and entropy, then combine them into a spontaneity judgement. Expect Hess's law, formation and bond enthalpies, calorimetry, entropy changes, and Gibbs energy linked to K and E°.
408 words, about 2 min06Chemical Equilibrium and Reaction Kinetics
Equilibrium and kinetics questions separate two ideas that students often blur: how far a reaction goes (K) and how fast it goes (rate). The paper tests equilibrium expressions, ICE tables and Le Chatelier reasoning alongside experimental rate laws, integrated rate equations, half-lives and Arrhenius behaviour.
405 words, about 2 min07Acids, Bases, and Salts (including pH and buffers)
Acid-base questions combine equilibrium arithmetic with titration reasoning. You need pH and pOH for strong and weak acids and bases, salt hydrolysis, buffer design and the shape of titration curves, including indicator choice.
422 words, about 2 min08Electrochemistry and Redox Reactions
Electrochemistry questions connect redox bookkeeping to cell potential and to the free-energy change that drives a galvanic cell or an electrolysis. Expect oxidation numbers, cell notation, E° cell, the Nernst equation, spontaneity and Faraday-type electrolysis calculations.
403 words, about 2 min09Organic Chemistry: Structure, Bonding, and Functional Groups
Organic structure questions test whether you can map a formula onto a bonding model, name the compound, and predict its physical and acid-base behaviour from functional-group effects. Expect hybridisation, resonance, aromaticity, isomer counting and systematic naming.
372 words, about 2 min10Organic Reactions and Mechanisms
Mechanism questions ask you to predict the major product and justify it with a mechanism. The exam tests substitution versus elimination competition, electrophilic addition, radical substitution, aromatic substitution patterns and carbonyl chemistry, plus the stereochemistry each pathway imposes.
371 words, about 2 min11Inorganic Chemistry: Periodicity, Coordination, and Descriptive Chemistry
Inorganic questions combine periodic trends, coordination chemistry and descriptive facts about the main groups. Expect to assign geometry and isomerism from a formula, apply crystal field theory to spin states and colour, and recall the solubility and acid-base patterns that distinguish the groups.
