Practically we prepare solution and analyze more than one sample in different periods to find concentration , after this if we plot concentration versus time to find on the normal graph paper, we will not get linear curve while if we plot the log of concentration versus time we paper will get linear equation.

If the Y-intercept = 90 mole/l … Co = 90 mole/l if we use the semi-log paper but if we use normal graph paper we must take the anti-log of y-intercept.
