Chapter 14, question 8, they're telling us, a is going to products.
00:10
In which of these graphs, we would expect them to be either zero to first or second order with respect to a.
00:19
So now we need to write the integrated rate laws.
00:24
Zero is going to be concentration of a at time t equals to minus kt, and concentration of a at zero.
00:48
So similarly, first order is going to be ln, concentration of a at a at a given time, equals to minus kt plus ln a0.
01:14
And second order is going to be this time, 1 over at, equals to minus kt, plus ln, a0.
01:26
To this time this is going to be a plus k t plus 1 over a 0 now all these three are integrated because we want to write this in such way y equals to mx plus b graph now y values are going to be all these first things in the equation.
02:04
Whereas the m values are k values, but also the signs of the k are important.
02:18
X are plotted with t.
02:22
So the time is going to be our x -axis.
02:27
And our constant b, which is basically telling us where this y graph is starting, are the last values...
