Part A The rate constant for a certain reaction is k = #7.00xx10^-3# #s^-1#. If the initial reactant concentration was 0.600 M, what will the concentration be after 19.0 minutes?
The units for
So we get:
Putting in the numbers:
This is 1st order exponential decay. The concentration / time graph looks like this:
You will notice that the time taken for
This is a feature of 1st order processes.
