example 15.4: Measuring a Rate Constant

Postby Paula Dowdell 1F » Sat Mar 03, 2018 1:51 pm

For the problem shown in example 15.4 we are supposed to, "Confirm that the reaction is first order in C3H6 and calculate the rate constant". The example then tells us to "Plot the natural logarithm of the reactant concentration as a function of t. If a straight line is obtained, the reaction is first order and the slope of the graph is k". This graph gives us the points needed to solve the problem.
I understand how the problem works but I was wondering if, on a test, we are going to be expected to do this sort of problem?
Thanks!

My TA said that it could end up on Test 3 and/or the Final, but I believe he mentioned that the numbers involved wouldn't be difficult to work with.

Yes you will be expected to determine orders and rate constants based on experimental data.
