OCR Gateway C3 (Chemical Economics) Revision Resource
I've often found that pupils don't link different parts of a unit together to see how they are connected. To this end, I've created a resource that merges together different aspects of the OCR Gateway C3 unit on Chemical Economics.
The booklet includes questions on atom economy, collision theory, percentage yield, batch and continuous and nanotubes. At the end, I have also included past exam questions.
The second document contains the answers to all questions.
Any comments and suggestions to improve this resource are welcome!
