The oxidation of sulfur dioxide to sulfur trioxide is an important reaction. At 1000K, the value of Kc is 3.6 x 10^-3. What is [SO3] at equilibrium when the reaction vessel is maintained at 1000K.

..............2SO2 + O2 ==> 2SO3
initial......
How much SO2 to start?

Whoops forgot that part of the question:

A closed flask originally contains 1.7 mol/L SO2 and O2.

...............2SO2 + O2 ==> 2SO3
initial........1.7 M..1.7M...0
change..........-2x....-x......2x
equil........1.7-2x....1.7-x...2x

Substitute the equilibrium values from the ICE chart above into the Kc expression for the reaction and solve for x. 2x is what you want.
