3. The reaction for vapor phase dehydration of ethanol to diethyl ether and water is, 2C;H:OH (C:Hs):0 + H20 This reaction was carried out at 120 °C over a solid catalyst. The following table shows some experimental data for the rate of following table shows some experimental data for the rate of reactiion as + a function of inlet partial pressures.

Using a graphical analysis, show that the proposed rate equation: k(P - Pw KEQ -TA= (1+ KAPA + KĘPE + Kw, Pw)2 Fits the above data reasonaby well. The parameter Keg is the equilibrium constant for the reaction at 120 °C, based on pressure units. 2. From your anaylsis, estimate the values for the rate constants k, the equilibrium constant Keq, and the adsorption equilibrium constants KA, KE, and Kw. 3.
