So the y axis is our natural log of x of our concentration of reactive and our x axis is time or progress or reaction. And we see that once again our slope is negative k, our Y intercept is this guy. And in order to find our K, we simply use the slope. In other words, change in y over change in x. Now once again, if our A equals one, then when we graph this equation on the XY plane, we should get a negative slope like this a straight line. Now, suppose our A was zero, and we tried graphing this equation the same way.
