![II.7- Saponification, initial rates and half-life
An esterification reaction is studied at 350 K under conditions where the reaction is complete:
ROH + R'COOH
→ R'COOR + H20
For the same initial alcohol concentration, and variable acid concentrations, we obtain the following
curves of evolution of the acid concentration versus time:
[R'COOH] (mol L'')
-0.8
-0.6
-0.4-
-0.2
40
60
80
100
120
140
160
180
200
The rate v of this reaction follows the law v = k[R°COOH]ª [ROH]F.
1) Explain how to graphically determine an instantaneous velocity (rate) at time t.
