List the following esters in order from most reactive to least reactive toward hydrolysis: There are three similar structures. Each structure contains a six-vertex ring with alternating single and double bonds and with an OCCH3 group attached to the first vertex. An O atom is double-bonded to the first (from left to right) carbon atom of the OCCH3 group. The first structure has no more substituents attached. The second structure has an NO2 group attached to the fourth (clockwise) vertex. The third structure has an OCH3 group attached to the fourth (clockwise) vertex.

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.
