Question

Consider the formation of X and X forming which occurs in two steps as shown below:

(i) W + 2X → 2Y ΔH° = +100 kJ

(ii) X + 2Y → 2Z ΔH° = –60 kJ

(iii) W + 3X → 2Z ΔH° = ?

Select the Hess's law diagram that best depicts the individual reactions and the overall process.

Accepted Answer

Alternative Hess's Law diagram illustrating the same reactions with different visual representation.

Answer

Hess's Law diagram showing two reaction pathways for W to Z via Y with energy changes.
