NOTE: use at least three non-zero decimal places in all calculations. a. Write the rate equation for the decomposition of a moderately adsorbed gaseous A on a solid, assuming that the surface decomposition is the rate determining step and that the adsorption of A follows Langmuir un-dissociative isotherm. [02 Marks] b. Derive the integrated rate equation for the decomposition of moderately adsorbed gaseous A on a solid , assuming that the surface decomposition is the rate determining step and that the adsorption of A follows Langmuir un-dissociative isotherm. [11 Marks] c. Show that following data for the decomposition of gaseous A on a solid at 25C satisfy the integrated rate law and calculate the values of the adsorption equilibrium constant and the rate constant at 25C.
