Chemical and Ionic Equilibrium - Result Question 48

####48. For the reaction, CO(g)+2H2(g)CH3OH(g)

hydrogen gas is introduced into a five litre flask at 327C, containing 0.2 mole of CO(g) and a catalyst, until the pressure is 4.92atm. At this point 0.1 mole of CH3OH(g) is formed. Calculate the equilibrium constant, Kp and Kc.

Solution:

  1. CO(g)+2H2(g)CH3OH(g)

Mole : 0.20.10x0.200.10 Total moles =x

x=4.92×50.082×600=0.5

moles of H2 at equilibrium =x0.2=0.3

Partial pressures : CO=0.10.5p,H2=0.30.5p,

CH3OH=0.10.5p

Kp=p5(p5)(35p)2=259p2=259(4.92)2=0.11atm2

Concentrations : [CO]=0.15M,[H2]=0.35M,

[CH3OH]=0.15MKc=(0.1/5)(0.1/5)(0.3/5)2=277.77M2
