Kinetics and Mechanism of the Reaction between Chromium(III) and 2,3-Dihydroxybenzoic Acid in Weak Acidic Aqueous Solutions

Figure 4

A typical non-linear plot of ln(𝐴𝑡−𝐴_∞) versus time. The value of ∆ that corresponds at time 𝑡=1×10³ s is shown. Conditions: [2,3-DHBA]₀=0.039M, [Cr(III)]₀ = 0.05 Μ, 𝑑=1 cm cell, and 𝑇= 289 K.
