Section 9 Part III
Figure 4 Amounts of A (unabsorbed ethanol), B (absorbed ethanol) and C (ethanol oxidized by LADH) according to the integrated rate laws for first-order / zeroth-order consecutive reactions. [A]0 = 1 mol ; k1 = 0.00289 s-1 ; k2 = 0.00004

9.3.2. First Order Kinetics Continued.
Rate = - d [A] / dt = k [A] [A] = [A]0 e
-kt
ln ([A]/[A]0) = - k t Plot of ln cfw_ [A] / [A]0 vs. t gives a straight line with a slope that is given by k
[A] = [A]0 e

.the direction of spontaneous change at constant T and P is towards lower values of Gibbs Energy (G). this also applies to chemical reactions
Gibbs energy of reaction (G).

9.8. Theories of Reaction Rates
We will consider one theory for reaction rates.
Transition State Theory
(please also take a look at Collision Theory in Chang text pages 473-474) .theory developed by Henry Eyring in the 1930s .enables us to calculate the r
