Hi experts! I need help with the following Questions 1. Derive Langmuir' adsorption isotherm for the following cases: (a) Molecular adsorption of CO (b) Dissociative adsorption of CO (c) Competitive adsorption of molecularly adsorbed CO and dissociative adsorbed H2, without further reaction (d) Give the expression for the fraction of unoccupied sites for (c) (e) Suppose the catalytic formation of methanol from CO and H2 occurs through a mechanism in which the reaction between adsorbed CO and the first H-atom determines the rate (the reverse reaction may be ignored), while all subsequent reaction steps are fast, except for the desorption of methanol, which may be considered at equilibrium with the gas phase. (i) Devise the mechanism (ii) Derive an expression for the rate of reaction (iii) Discuss the range of values that the orders in hydrogen, carbon monoxide and methanol may assume if hydrogen adsorbs more weakly than the other gases
