Ag(I) Catalyzed Grafting of Acrylonitrile onto Gum Arabic by Ce(IV) in H₂SO₄ Medium: A Kinetic Study

Figure 2

(a) Effect of [GA] on rate of grafting (𝑅_g). Plot of 5 + log𝑅_g versus 2 + log[GA] in presence and absence of Ag(I). [(Ce(IV)] =5.00×10⁻³ M, [AN] =4.00×10⁻² M, Temp = 313°K, [H₂SO₄] =0.1 M, [Ag(I)] =1.00×10⁻² M. (b) Effect of [Ag(I)] on Rate of grafting (𝑅_g), Plot of 5 + log𝑅_g versus 2 + log[Ag(I)]. [GA] =10×10⁻²%(w/v), [AN] =4.00×10⁻² M, Temp = 313°K, [H₂SO₄] =0.1M, [(Ce(IV)] =5.00×10⁻³ M.
