🤓 Based on our data, we think this question is relevant for Professor Jurisch's class at UIC.

Solution: At constant pressure, which of these systems do work on the surroundings? A. 2A(g) + 3B(g) → 4C(g)B. A(s) + B(s) → C(g)C. 2A(g) + 2B(g) → 3C(g)D. 2A(g) +B(g) → 4C(g)E. More than one of the above 

Problem

At constant pressure, which of these systems do work on the surroundings? 

A. 2A(g) + 3B(g) → 4C(g)

B. A(s) + B(s) → C(g)

C. 2A(g) + 2B(g) → 3C(g)

D. 2A(g) +B(g) → 4C(g)

E. More than one of the above 

Solution

Recall: When the system does work on the surroundings, the sign for work (w) is negative (w <  0). On the other hand, work is positive (w > 0) if the surroundings do work on the system. To illustrate
