Calculate ΔS° for the following reaction: ​ 2 SO3(g) → 2 SO2(g) + O2(g). ​ ΔS° in J/moles K for SO2(g) is 248.1, for SO3(g) is 256.6, and for O2(g) is 205.0.

Without detailed calculations, predict the sign of ΔS for the following reaction: ​ Mg(s) + O2(g) → MgO(s)

The rate of a reaction depends on the concentration of the reactants.
