Calculating Gradients (AQA GCSE Chemistry Combined Science): Flashcards

How steep a line is

How quickly reaction is happening at specific time

To find rate of reaction at any particular moment

Line touching curve at one point, doesn't cross it

Draw a tangent at point of interest

Change in amount of substance

Change in time

$\frac{\text{Change in Amount}}{\text{Change in Time}}$

$5 \text{ cm}^3/\text{s}$

Measure rate at specific moment, not average
