Consider the case of finding equilibrium concentrations in cases with small equilibrium constants for the following
reaction.
2H2S(g) 2H2(9) + S2(g) Kc=1.67X107 at 800 °C
A0.500 L reaction vessel initially contains 0.0125 mol of H,S at 800 °C while the initial concentrations of Hz and
Sz are 0.00 mol. The equilibrium concentration of S2 was calculated as 2.97X104 mol using the approximation
method. In this case, the small approximation assumption is VALID, so the quadratic equation DOES NOT need
to be used to determine X.
