Question

Which of the following reactions shows that the formation of SO2 releases
296.8 kJ/mol?
O A. S(s) + O(g) → SO2(g) + 296.8 kJ
O B. S(s) + O2(g) → SO2(g) + 296.8 kJ
O C. S(s) + 20(g) + 296.8 kJ → SO2(9)
O D. S(s) + O2(g) + 296.8 kJ → SO2(g)

Answer 1

Answer:

S(s) + O2(g) --> SO2(g) + 296.8 kJ

Explanation:

Answer 2

The reaction that shows the formation of SO₂ is:

B. S(s) + O₂(g) → SO₂(g) + 296.8 kJ

Formation of SO₂:

The reaction for the formation of sulfur dioxide is an exothermic reaction as the heat is released instead of being absorbed.

When a gas condenses to a liquid, heat is given off and the process is exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants.

Thus, correct option is B i.e. S(s) + O₂(g) → SO₂(g) + 296.8 kJ
