I need help with writing an equation

Question

How would you write a algebraic equation, using the table, that shows how to find ΔH of this reaction?

Answer 1

ΔH = Σ ΔH^o = v + w + (x/2) + y + z

K(s) → K(g) ΔH^o = v

K(g) → K⁺(g) + e^– ΔH^o = w

(1/2) [Cl₂(g) → 2 Cl(g)] ΔH^o = x/2

Cl(g) + e^– → Cl^–(g) ΔH^o = y

K⁺(g) + Cl^–(g) → KCl(s) ΔH^o = z

Please let me know if anything doesn't make sense!
