Two galvanic cells with two different chemical reactions are given. The value of E ° for both the cells is to be calculated. Concept introduction The galvanic cell converts chemical energy into electrical energy while the electrolytic cell converts electrical energy into chemical energy. The species at anode undergoes oxidation while the species at cathode undergoes reduction and the electrons generated at the anode are transferred through wire to the cathode.

How do I solve this Alkyne synthesis homework problem for my Organic Chemistry II class? I have to provide both the intermediate products and the reagents used.
Substance X is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature. Additionally, the values of these other properties of X
have been determined:
melting point
enthalpy of fusion
90. °C
8.00 kJ/mol
boiling point
130. °C
enthalpy of
vaporization
44.00 kJ/mol
density
2.80 g/cm³ (solid)
36. J.K mol (solid)
2.50 g/mL (liquid)
heat capacity
32. J.Kmol (liquid)
48. J.Kmol (vapor)
You may also assume X behaves as an ideal gas in the vapor phase.
Ex
Suppose a small sample of X at 50 °C is put into an evacuated flask and heated at a constant rate until 15.0 kJ/mol of heat has been added to the sample.
Graph the temperature of the sample that would be observed during this experiment.
