73. Consider the decomposition of the compound CHO3 as follows: C,HO3(g) CH,(g) + 3CO(g) When a 5.63-g sample of pure C,H,O3(g) was sealed into an otherwise empty 2.50-L flask and heated to 200.C, the pres- sure in the flask gradually rose to 1.63 atm and remained at that value. Calculate K for this reaction. -31 74. At 25C, Kp 1 X 10 for the reaction P N(g) + O(g)2NO(g)
