When 1-pentyne (A) is treated with 4N alcoholic KOH at 175°C, it is converted slowly into an equillibrium mixture of 1.3% 1-pentyne (A), 9.5% 2-pentyne (B) and 3.5% of 1.2-pentadiene (C) .The equillibrium was maintained at 175°C. Calculate ΔG° for the following eqilibria.

B ↔ A, ΔG°1=??

B ↔ C, ΔG°2=??

From the calculated value of ΔG°1 & ΔG°2 indicate the order of stabiity of (A), (B), & (C). Write a reasonable reaction mechanism showing al intermediates leading to (A), (B) & (C).

Dear student, Gibbs Free Energy (G) - The energy associated with a chemical reaction that can be used to do work. The free energy of a system is the sum of its enthalpy (H) plus the product of the temperature (Kelvin) and the entropy (S) of the system: Free energy of reaction ( G) The change in the enthalpy ( H) of the system minus the product of the temperature (Kelvin) and the change in the entropy ( S) of the system: Standard-state free energy of reaction ( G ) The free energy of reaction at standard state conditions: Standard-state conditions The partial pressures of any gases involved in the reaction is 0.1 MPa. The concentrations of all aqueous solutions are 1 M. Measurements are also generally taken at a temperature of 25 C (298 K) Please feel free to ask your queries here.
