Chemistry & Technology · Part 4 of 4
3 exam-style questions with model answers, plus 4 quick multi-choice questions — every question on this part of the standard, grouped by the 1 page of notes they come from.
Write a full answer before you reveal the model one. That comparison is where the learning happens.
Name the three pollutants removed by a three-way catalytic converter, state where each comes from, and write a balanced equation for the reaction that removes each.
Explain why the catalyst metals are coated onto a ceramic honeycomb, and link this to both the rate of reaction and the cost of the technology.
Evaluate how the chemistry of catalysis influenced the development of vehicle emissions technology and of fuel policy in New Zealand.
