1) Determine the average rate of product
formation between 50 and 150 seconds.

Time (s)
The
at a single time is the
rate.
The slope over a range of time is the
rate.
Connection to Mathematics & Physics
Slope is the rate of change. The symbol
(delta) means
"for a range (average rate of change).
Example: A car decreases speed from 35 m/s to 15 m/s over a period of 5 seconds.
What is the car's acceleration (average rate of change for velocity)?
Example: The concentration of CHaF product increases from 0.20 mol/L to 0.80 mol/L
over 12 seconds of reaction time. Determine the average reaction rate for this time.
CH4 + F2 CH3F + HF
