Effect of Concentration on the Rate of Production of Oxalic Acid from the Bark of Eucalyptus Camaldulensis

Abstract

The kinetic studies on the rate of production of Oxalic acid from the bark of of Eucalyptus camaldulensis was analysized using integral and differential methods of analysis using solvent concentration of 3 and 4% H_2 〖SO〗_4. 3% H_2 〖SO〗_4 recorded a rate constant of 0.0389 (integral) and 0.0375 (differential) and rate equation -r_A= 0.0389〖C_A〗^2 (integral ) and -r_A= 0.0375〖C_A〗^2 (differential) while 4% H_2 〖SO〗_4 recorded a rate constant of 0.0446 (integral) and 0.0478 (differential) and rate equation -r_A= 0.0446〖C_A〗^2 (integral ) and -r_A= 0.0478〖C_A〗^2 (differential). The result revealed that the rate order of reaction is the same for both percentage of H_2 〖SO〗_4 and that a better yield was recorded with 4% percent H_2 〖SO〗_4 concentration.
