Rate Factors Lab

How to use: Move the two time sliders along the graph. The tool shows [A] at each time and finds the average rate. Try the cool, room and warm choices.

Conditions Time 1: 0 s Time 2: 30 s

[A] at time 1 = M
[A] at time 2 = M

Average rate = (change in [A]) ÷ (change in time)

t (s)	0	30	60	90
[A] (M)
