Kinetic parameters
The values of the kinetic parameters and the individual error estimates for the nonlinear kinetics of hyperbolic and pseudo second order models are presented in Table 1. In Table 1, it could be observed that majority of the kinetic parameters of C1 and Csfor hyperbolic and Pseudo second order models, respectively, increased with the increase in temperature. This could be attributed to the reason behind the increase in the oil yield as temperature increased [18,42]. Similarly, the kinetic parameters of C2 and K also increased with increase in temperature as could be observed in Table 1. This increase in oil yield with temperature was as a result to the thermodynamic effect of oil solubilization inside the solid seed particles [32]. The observations in the kinetic parameters of the hyperbolic and Pseudo second order models, were in line with the results obtained by Kitanovic et al. [19] and Agu et al. [56] for the solvent extraction of resinoid from aerial part of Hypericum perforatum L and extraction of oil from Colocynthis vugaris Shrad seed, respectively.
