In a constant-pressure process, ΔH = 0. What can you conclude about ΔE, q, and w?

1. If ΔH = 0, qp = w and ΔE = 0.
2. If ΔH = 0, qp = ΔE and w = 0.
3. If ΔH = 0, qp = 0 and ΔE = 0, w = 0.
4. If ΔH = 0, qp = ΔE = w.
5. If ΔH = 0, qp = 0 and ΔE = w.

Hi adrii01,

At constant pressure,
ΔE = q + w    and   ΔH = q
if ΔH = 0, therefore q = 0

Rightwards Arrow ΔE = w

Best,

Would that be choice #4 then? If so, it says it's incorrect...
