Consider the decomposition of the compound C5H6O3 as follows below.
C5H6O3(g) → C2H6(g) + 3 CO(g)
When a 5.63-g sample of pure C5H6O3(g) was sealed into an otherwise empty 2.50 L flask and heated to 200.°C, the pressure in the flask gradually rose to 1.63 atm and remained at that value. Calculate K for this reaction.
