Use the Standard Reaction Enthalpies Given Below to Determine Δ_rH°

Use the standard reaction enthalpies given below to determine Δ_rH° for the following reaction: 2S(s) + 3O₂(g) → 2SO₃(g) Δ_rH° = ?
Given:
SO₂(g) → S(s) + O₂(g) Δ_rH° = +296.8 kJ
2SO₂(g) + O₂(g) → 2SO₃(g) Δ_rH° = -197.8 kJ

A) -494.6 kJ mol^-1
B) -692.4 kJ mol^-1
C) -791.4 kJ mol^-1
D) 1583 kJ mol^-1
E) -293.0 kJ mol^-1
