Carefully graph ln[H + ] on the y-axis and t on the x-axis, drawing a line of best fit. Use your calculator to
perform a linear regression. Carefully graph 1/[H + ] on the y-axis and t on the x-axis, drawing a line of best
fit. Use your calculator to perform a linear regression. Note: there are many other ways to represent this
graph with the data/calculations listed above. It is up to you to understand the math and the relationships of
these variables to the line equation.
Which graph is linear
What is the slope of the graph
What is the y-intercept
What is the order of the reaction with respect to hydrogen ions
Determine the value of the rate constant.
Post-Lab Questions:
1. Why does reaction rate usually change as the concentration changes
2. Why does the reaction rate usually change with temperature
3. What is the difference between reaction rate and specific rate constant
4. How could you improve your data
