How Do You Determine the Rate of Reaction? The reaction rate, or the speed that the reaction happens at, is written as the change in concentration of a reactant or product per change in time as shown above. In order to calculate this experimentally you have to monitor either the concentrat...
This paper deals with interactions among three kinds of nonlinear mechanisms: nonlinear diffusion, nonlinear reaction and nonlinear boundary flux in a parabolic model with multiple nonlinearities. The necessary and sufficient blow-up conditions are established together with blow-up rate estimates for the ...
