ΔH and ΔU are nearly the same in all the following processes except A)F₂(g)+ H₂(g)→ 2HF(g). B)CH₄(g)+ Cl₂(g)→ CH₃Cl(g)+ HCl(g). C)C₆H₆(s)→ C₆H₆(l). D)CuO(s)+ H₂(g)→ Cu(s)+ H₂O(g). E)3O₂(g)→ 2O₃(g).

Question

Quizplus · Accepted Answer

In the process 3O₂(g)→ 2O₃(g), there is a change in the number of moles of gas, which affects the work done by the system and thus the difference between ΔH and ΔU.
