Common mistakes
- Do not mix up time for the reaction to finish with rate. A shorter time means a higher rate.
- Pressure only matters for gases. Heating a solution is temperature, not pressure.
- A catalyst does not give particles extra energy, does not increase temperature by magic, and does not change yield. It lowers the energy barrier.
- Do not plot time on the y-axis and call it rate. Rate goes up when time goes down.
