The rate of hydrolysis of sucrose to glucose and fructose is quite slow in the absence of a catalyst. If the initial concentration of sucrose is 0.050 M, it takes 440 years for the concentration of the sucrose to decrease by half to 0.025 M. What is the rate of disappearance of sucrose in the absence of a catalyst

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night. when he took it out, its new volume was 322 milliliters, but its pressure was the same. if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is kelvins.

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.
