In a reversible reaction, carbon monoxide gas and hydrogen gas are mixed to produce methanol gas (CH3OH). The enthalpy change of this reaction is AH = 90 kJ mol A mixture of 0.360 moles of CO and 0.640 moles of H2 were allowed to reach equilibrium at 150°C in a 10 dm' sealed container. At equilibrium the mixture contained 0.120 moles of CH,OH. (a) Calculate the K for this reaction (to 1.d.p). (10 marks) Similarly to Ko, K is an...

4.66. Methanol is formed from carbon monoxide and hydrogen in the gas-phase reaction CO 2H2 CH3OH (A) (B) (C) The mole fractions of the reactive species at equilibrium satisfy the relation 1 = Ke(T where P is the total pressure (atm), Ke the reaction equilibrium constant (atm2), and T the temperature (K). The equilibrium constant Ke equals 10.5 at 373 K, and 2.316 x 10-4 at 573 K. A semilog plot of Ke (logarithmic scale) versus 1/T (rectangular scale) is...

A chemical engineer is studying the following reaction: 2 H,S(9)+302(9) - 2 SO2(9)+2H2O(9) At the temperature the engineer picks, the equilibrium constant K, for this reaction is 4.1. The engineer charges ("hills") four reaction vessels with hydrogen sulfide and oxygen, and lets the reaction begin. She then measures the composition of the mixture inside each vessel from time to time. Her first set of measurements are shown in the table below. Predict the changes in the compositions the engineer should...
