Consider the following reaction in the vessel described in Question 57.

For this reaction, ΔE = 286 J, the piston moves up and the system absorbs 388 J of heat from its surroundings.

(a) Is work done by the system?

(b) How much work?

Reference Question 57:

Consider the following reaction in a vessel with a movable piston.

As the reaction occurs, the system loses 1185 J of heat. The piston moves down and the surroundings do 623 J of work on the system. What is ΔE?
