2 O3(g)→ 3 O2(g) The reaction would have a _______ △S. A) positive B) negative C) zero D) can't determine from given information Why? (pick one) A) The moles of gas increase B) The moles of gas decrease C) The moles of gas remain constant. D) The total moles of product are greater E) The total moles of reactant are greater. F) The number of moles are the same in reactants and products
Ozone, O3, is an important absorber of UV radiation in our atmosphere. Upon absorption of UV radiation, O3 dissociates into molecular oxygen, O2, and a free oxygen atom. The free oxygen atom can then join with another O2 molecule to create more ozone, which can in turn absorb more UV radiation. Alternatively, the free oxygen atom could join with O3 to create more O2.
