Question

For each of the following processes, identify the system and the surroundings. Identify those processes that are spontaneous. For each spontaneous process, identify the constraint that has been removed to enable the process to occur: A solution of hydrochloric acid is titrated with a solution of sodium hydroxide. Zinc pellets dissolve in aqueous hydrochloric acid. A rubber band is slowly extended by a hanging weight. The gas in a chamber is rapidly compressed by a weighted piston. A tray of water freezes in the freezing compartment of an electric refrigerator.

Explanation / Answer

For the given set of systems

(a) System : HCl and NaOH

Surrounding : water

constraint removed : all the heat is absorbed by water

(b) System : Zn and HCl

Surrounding : water

constraint removed : all the heat is absorbed by water

(c) System : rubber band

Surrounding : hanging weight

constraint removed : all the heat is is given to rubber band

(d) System : gas

Surrounding : piston

constraint removed : all the heat is given by piston

(e) System : water

Surrounding : refrigerator

constraint removed : all the heat is absorbed by refrigerator insulated
