Figure 1

(a) Effect of [GA] on rate of oxidation. Plot of 4 + log𝑅_oxiversus 2 + log[GA]. [Ag(I)]=1.00×10⁻² M, [Ce(IV)] =5.00×10⁻³ M, [H₂SO₄] =0.1 M, [AN] =4.00×10⁻² M, and Temp = 313°K. (b) Effect of [Ag(I)] on rate of oxidation. Plot of 4 + log𝑅_oxi versus 2 + log[Ag(I)]. [GA] =10×10⁻²%(w/v), [Ce(IV)] =5.00×10⁻³ M, [H₂SO₄] =0.1 M, [AN] =4.00×10⁻² M, and Temp = 313 K.
