At one time, a common means of forming small quantities of oxygen gas in the laboratory was to heat KCIO3:

2 KCIO3(3) -----> 2 KCI(s) + 3 O2(g) ?H= -89.4 kj

For this reaction, calculate ?H for the formation of (a) 1.36 mol of O2 and (b) 10.4 g of KCI. (c) The decomposition of KCIO3 proceeds spontaneously when it is heated. Do you think that the reverse reaction, the formation of KCIO3 from KCI and O2, is likely to be feasible under ordinary conditions?
