Methanol (C) is formed from carbon monoxide (A) and hydrogen (B) in the gas-phase reaction

CO + 2H2 CH3OH

The mole fractions of the reactive species at equilibrium satisfy the relation

where P is the total pressure (atm), Keq the reaction equilibrium constant (atm2) , and T the temperature (K). The equilibrium constant Keq equals 10.5 at 373 K, and 2.316 x 104 at 573 K. A semilog plot of Keq(logarithmic scale) versus 1/T (rectangular scale) is approximately linear between T = 300 K and T = 600 K.

a. What is the value of log 10(Keq*(1 atm)4) at T= 421 K? i b. Suppose you begin with a molar ratio of CO/H2 = 0.900 and no methanol. If the reaction proceeds to equilibrium at 421 K and 2 atm, calculate the molar composition of the product and the fractional conversion of CO. yco: i , : Ma i , : PO i Fractional Conversion: i c. Repeat the calculation for a molar ratio of CO/H2 = 1.150. Yco: , : i , : Fractional Conversion: Me eTextbook and Media Save for Later Attempts: 0 of 3 used Submit Answer
