What would be the reagents and conditions above and below the arrow that will complete the proposed acetoacetic ester synthesis? If it cannot be done efficiently, then I will choose that answer. There could be 2 or 4 reagents involved. Please provide a detailed explanation and drawings showing how it would proceed with the correct reagents.

For benzene, the ∆H° of vaporization is 30.72 kJ/mol and the ∆S° of vaporization is 86.97 J/mol･K. At 1.00 atm and 228.0 K, what is the ∆G° of vaporization for benzene, in kJ/mol?

The reaction Q(g) + R(g) → Z(l) is shown to be exothermic. Which of the following is true concerning the reaction.  it is spontaneous only at High T, it is spontaneous at low T  it is nonspontaneous at all T it is spontanrous at all T.  it is non spontaneous only at low T.
