Problem: Three gas-phase reactions were run in a constant-pressure piston apparatus as shown in the following illustration. For each reaction, give the balanced reaction and predict the sign of w (the work done) for the reaction.If just the balanced reactions were given, how could you predict the sign of w for a reaction?
