Without consulting tables of ΔHf°, ΔS°, or ΔGf°, predict the temperature dependence of favorability for each of the two reactions given. Enter an answer for each reaction. 2 NO2(g) → N2O4(g) always favored favored at high temperatures favored at low temperatures C5H12(g) + 8 O2(g) → 5 CO2(g) + 6 H2O(g) always favored favored at high temperatures favored at low temperatures

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
