Solution
The reaction that would not involve any work is "the mixing of an acid and a base to form water and a salt". This is because work in physics is defined as a force causing the movement—or displacement—of an object. In the given options, the first three involve displacement or movement (vaporization involves movement of particles from liquid to gas state, explosion involves gases pushing outwards, and expansion of a piston involves movement of the piston due to gas pressure). However, the mixing of an acid and a base to form water and a salt is a chemical reaction that occurs on a molecular level and does not involve any macroscopic displacement or movement, and therefore does not involve any work in the physical sense.
