Consider the following reaction, equilibrium concentrations, and equilibrium constant at a particular temperature. Determine the equilibrium concentration of SO2(g).

Question

2SO2(g)+O2(g)=2SO3(g) Kc=1.7*10^8
[SO3]aq=0.0034 M
[O2]aq=0.0018 M

Answer 1

K=[SO3]^2 /[O2][SO2]^2

Put in the numbers, solve for the concentration of SO2

Answer 2

1.9M
