7.4 Hydrogen peroxide decomposes to produce
water and oxygen. The equation is:
2H, O2(g) → 2H, O(g) + O2(g)
Using the following values, calculate the heat
change for the reaction and say whether it is
exothermic or endothermic.
Bond energies:
H—H = 436 kJ/mol
00 = 144 kJ/mol
0=0 = 498 kJ/mol
0-H = 464 kJ/mol

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
