Question
Consider the following changes:
a.N2 (g) → N2 (l)
b.CO (g) + H2O (g) → H2 (g) + CO2 (g)
c.Ca3P2 (s) + 6H2O (l) → 3Ca(OH)2 (s) + 2PH3 (g)
d.2CH3OH (l) + 3O2 (g) → 2CO2 (g) + 4H2O (l)
e. I2 (s) → I2 (g)
At constant temperature and pressure, in which of these changes is work done by the system on the surroundings? By the surroundings on the system? In which of them is no work done?
