Answer:

B.) –197.8 kJ

Balanced equation : 2SO₂(g) + O₂(g) → 2SO₃(g)

Given:

  • SO₂(g) = –296.8 kJ/mol
  • SO₃(g) = –395.7 kJ/mol

================================================================

  • products : 2 ( –296.8 ) + O₂ = -593.6 kJ/mol + O₂
  • reactant : 2 (  –395.7 ) = -791.4 kJ/mol

products energy = reactant energy

-593.6 + O₂ = -791.4

O₂ = -791.4 - ( -593.6)

O₂ = –197.8 kJ
