Question

When the following equilibrium process

CO + 2H2(g) =CH2OH()
reached equilibrium in a particular experiment, the following equilibrium
concentrations were present.
[CO]=0.150M
[Hz]=0.360M
(CH3OH]=0.282M
Calculate the value of keq
?

Answer 1

K(eq) = 15 (2 sig. figs)

Step-by-step explanation:

Rxn: CO(g) + 2H₂(g) ⇄ CH₃OH(l)

C(eq): 0.150M 0.360M 0.282M

Keq = [CH₃OH(l)]/[CO(g)][H₂(g)]

= (0.282M)/(0.150M)(0.360M)²

= 14.50617284 (calc. ans.)

= 15 (2 sig. figs.)
