Brainlag PlusRates per minute and 1000 ÷ time, gradients, reading an optimum and an intercept, and choosing a chart.
Rates
- Count in a time: rate = amount ÷ time (bubbles per minute, cm³/min).
- Time to finish: rate = 1000 ÷ time (amylase, reaction times).
- From a straight-line graph: rate = gradient.
Read an optimum at the peak of a curve. In osmosis, the concentration where the best-fit line crosses 0% change in mass is the concentration of the cell contents.
