Query: Solutions of the Fractional Reaction Equation and the Fractional
  Diffusion Equation   In view of the role of reaction equations in physical problems, the authors
derive the explicit solution of a fractional reaction equation of general
character, that unifies and extends earlier results. Further, an alternative
shorter method based on a result developed by the authors is given to derive
the solution of a fractional diffusion equation. Fox functions and
Mittag-Leffler functions are used for closed-form representations of the
solutions of the respective differential equations.
