Higher practice prelim full paper 3

The third full-length Higher Chemistry paper, with all-new questions and contexts, for the final run-up to the prelim.

What’s included:

• Question paper: 20 multiple-choice questions with an answer grid, plus 80 marks of written questions (100 marks in total, in the new one-paper format)
• Full marking instructions: expected answers, step-by-step working for every calculation, and guidance on what to accept
• Covers Chemical changes and structure, and Nature’s chemistry
• Suggested time: 2 hours 30 minutes

Topics include the bonding and melting points of the period 2 elements, isomers with very different boiling points, a concentration and rate investigation with a graph to draw, the alcohol breathalyser, esters, fats and soaps, the amide link, and free radicals in skin care. There are two open-ended questions: why a catalytic converter works better once the engine is warm, and whether butter, olive oil and margarine really behave the same way.
