2 past paper questions on energy and chemical change from KwaZulu-Natal, 2025. Read what each one asks, then open it with its memo.
1 question on energy and chemical change. Each opens in the question browser with its memo.
A reversible reaction A₂ + B₂ ⇌ 2AB is shown on an energy diagram. Learners determine whether the forward reaction is endothermic or exothermic, calculate ΔH, define activation energy, compare bond strengths, and sketch the effect of a catalyst.
1 exam page where energy and chemical change appears alongside other topics — multiple-choice pages, and pages where one question ends and the next begins. Listed in full so nothing is hidden.
Multiple-choice questions covering: conjugate acid-base pairs of hydrogen phosphate; exothermic processes; Boyle's Law; and deviation of real gas behaviour from ideal behaviour.
