Chapter 19, Problem 19C.1DQ

Interpretation Introduction

Interpretation:

The essential features of the Langmuir-Hinshelwood and Eley-rideal mechanisms has to be described.

Concept introduction:

The mathematical expression of the Langmuir isotherm is given as,

  $\begin{array}{l}\text{θ}\text{=}\frac{\text{αp}}{\text{1+αp}}\text{;}\text{α}\text{=}\frac{{\text{k}}_{\text{a}}}{{\text{k}}_{\text{d}}}\\ \\ {\text{k}}_{\text{a}}\text{-}\text{Rate}\text{constant}\text{for}\text{adsorption}\\ \\ {\text{k}}_{\text{d}}\text{-}\text{Rate}\text{constant}\text{for}\text{desorption}\\ \\ \text{θ}\text{-}\text{Fractional}\text{coverage}\\ \\ \text{p}\text{-}\text{Partial}\text{pressure}\text{.}\end{array}$
