Rates of Chemical Reactions — JAMB Chemistry Past Questions
Rates of Chemical Reactions is one topic inside the JAMB Chemistry syllabus, and drilling it on its own is usually faster than revising the whole subject again. Below: which JAMB years have examined it, then real Rates of Chemical Reactions questions with worked answers.
When JAMB examined Rates of Chemical Reactions
Rates of Chemical Reactions questions appear in our bank for the JAMB years below. This is taken from the questions themselves, not from a syllabus outline — so if a year is listed, this topic was genuinely examined that year.
A topic that keeps reappearing is a topic JAMB keeps testing. Newer years matter most, because question style drifts.

Check the answerWhy do most chemical reaction rates increase rapidly as the temperature rises?
- A A. The fraction of molecules with higher kinetic energy increases
- B B. Activation energy increases as temperature rises
- C C. Activation energy decreases as temperature rises
- D D. More collision take place between particles so that the reaction can occur
