GCSE Chemistry - Measuring Rates of Reaction from Graphs - Mean Rate & Rate at a Specific Time

Подробнее о видео

⭐️ ⭐️

*** WHAT'S COVERED ***
1. Calculating the rate of reaction from a graph.
* Understanding the difference between the mean rate of reaction and the rate at a specific point in time.
2. How to determine the mean rate of reaction over a specific period.
* Reading values from a 'product formed vs. time' graph.
3. How to determine the rate of reaction at a specific moment.
* The technique of drawing a tangent to the curve at a particular point.
* Calculating the gradient of the tangent to find the instantaneous rate.
4. Applying calculation methods to different graph types.
* Graphs showing product formation over time.
* Graphs showing the amount of reactant remaining over time.
