Question 2 The kinetics of the synthesis of methanol has been studied experimentally. Since the reaction occurs in the gas phase, the amount of reactants and products is monitored in terms of their partiai pressure. The following initial reaction rates (in the absence of the product methanol) have been determined based on the change of the partial pressure of H2, namely - partial pressures of the reactants were varied. while the initial 2 dt PH, 0 Pco.o 0.05 bar 0.05 bar 1.14 x 10 bar/s 4.55 x 10 bar/s 2.27 x 10 bar/s 0.10 bar 0.05 bar 0,05 bar 0.10 bar Determine the overall order of the rate law for this reaction based on the general form: = k-(P, )" (Pco )" dt o order 1 order 2 order O 30 order

Methanol is a liquid at room temperature with a boiling point of 64.7°C. It can be synthesized from a mixture of carbon monoxide and hydrogen called synthesis gas in the following reaction. CO(g) + 2 H2 (g) H3COH(1) At 25 C, the standard reaction enthalpy A, He for this reaction is -128.05 kJ/mol and the standard reaction entropy A,S is -332.56 J/(K mol). CO and H2 gases can be treated as ideal gases. The molar heat capacity of methanol liquid at 25°C is Cm=81.11 J/(K mol) and of methanol in the gas phase at 77°C is 52.29 J/(K mol). The vaporization molar enthalpy for methanol is 35,200 J/mol.
