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 an object to move. In this reaction, there is no physical movement of an object due to a force. The other reactions involve physical movement - the expansion of a piston, the vaporization of boiling water causing steam to rise, and the formation of gases causing an explosion.
