For the following example, identify the following.
3O2 (g) → 2O3(g)
| 1) | a negative ΔH and a negative ΔS | |
| 2) | a negative ΔH and a positive ΔS | |
| 3) | a positive ΔH and a positive ΔS | |
| 4) | a positive ΔH and a negative ΔS | |
| 5) | It is not possible to determine without more information. |
Please type. No handwriting please.
Please explain step by step because I need to learn.

Answer
Chaos is being reduec, since 3 molecules of gas now form 2 molecules of gas
clearly dS decreases, so entropy must be NEGATIVE
for enthalpy, this must be positive, since bonds are being broken down, as well
the triple bond of Ozone requires much more energy than the O=O bonds so we need an energy inlet, i.e. the ENDOTHERMIC process
choose positive dH
from th elist, choose 4
