問題詳情

16. Consider the decomposition equation of a compound: C5H6O3(g)

C2H6(g) + 3CO(g). When a 5.63-g sample ofpure C5H6O3(g) was sealed into an otherwise empty 2.50-L flask and heated to 200℃, the pressure in the flask gradually rose to1.63 atm and remained at that value. The K value for this reaction is .
(A) 3.89 × 10-1
(B)6.74 × 10-6
(C) 8.00 × 10-2
(D) 4.00 × 10-3
(E)1.20 × 10-9
