Many one-dimensional transient diffusion-reaction problems in chemical systems involve solving partial differential equations (PDES). One such PDE has the form: a (ac 1 (aCy ac дх (дх, VEləx, at Treat all quantities here as dimensionless. Using combination of variables, i.e., n = x/Vt, prove that the partial analytical solution to the above PDE involves the following expression: C = A + B | eln+an²]dn Here A and B are constants of integration. Determine the value of the constant a. Do not apply any boundary conditions and / or determine the constants of integration.
