Consider the decomposition of the compound C5H6O3 as follows: C5H6O3(g) C2H6(g) + 3CO(g) When a 5.63-g

Question:

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