NZ Scholarship Chemistry study plan

Map the full Scholarship Chemistry specification into a one-page checklist of assessable skills, splitting it into structure and bonding, energetics and equilibrium, organic mechanisms, redox and electrochemistry, and analytical/inorganic descriptive chemistry, and rate your current confidence in each on a 1-5 scale.

Derive and explain the origin of the three 'big ideas' that recur across Scholarship questions: structure determines properties, energy and entropy drive change, and electron movement explains reactivity, writing a two-sentence justification for each.

Rebuild the thermodynamics toolkit from first principles: define enthalpy, entropy and Gibbs energy, derive ΔG = ΔH − TΔS, and state the conditions for spontaneity at high and low temperature with one worked example of each.

Practise 10 multistep calculation items combining Hess's law, bond enthalpies and calorimetry, showing full working and unit tracking, and log every arithmetic or sign error in an error journal.

Set up a spaced-repetition deck of at least 60 cards covering definitions, standard conditions, sign conventions and key equations, reviewed on days 1, 3 and 7.

Explain equilibrium quantitatively using Kc, Kp and reaction quotient Q, and predict the direction of shift for changes in concentration, pressure and temperature, distinguishing kinetic from thermodynamic effects.

Derive and apply the relationship between ΔG° and K (ΔG° = −RT ln K), and calculate K from electrochemical and thermodynamic data for at least three reaction types.

Analyse acid-base equilibria including weak acid/base approximations, buffers using the Henderson-Hasselbalch relationship, and titration curves, sketching and labelling at least four curve types.

Solve 8 structured equilibrium problems under timed conditions (12 minutes each), including one involving coupled equilibria or solubility product.

Write a 150-word explanation, in exam register, of why a catalyst changes rate but not equilibrium position, citing the energy profile.

Construct and interpret mechanism pathways for substitution (SN1/SN2), elimination (E1/E2) and addition reactions, predicting major products from substrate, nucleophile, solvent and temperature.

Draw curly-arrow mechanisms for at least 12 reactions, including carbocation rearrangements, Markovnikov addition and stereochemical outcomes, marking any stereocentre configuration changes.

Explain aromaticity using Hückel's rule and apply it to predict reactivity and directing effects in electrophilic aromatic substitution.

Link mechanism to spectroscopy: assign key IR stretches and interpret simplified 1H and 13C NMR splitting and chemical shift patterns for at least six functional groups.

Consolidate redox and electrochemistry: assign oxidation states, balance complex half-equations in acid and base, and calculate cell potentials and feasibility from E° values.

Apply the Nernst equation to non-standard conditions and explain how concentration and pH shift electrode potential, with two worked examples.

Interpret and sketch a Latimer or Frost diagram to judge disproportionation and comproportionation for a transition-metal series.

Sit a 90-minute mixed mock covering weeks 1-4 content and classify every lost mark as knowledge gap, method error or misreading.
