The equilibrium constant of the reaction 2 C 3 H 6 (g) C 2 H 4

Question:

The equilibrium constant of the reaction 2 C₃H₆(g) ⇌ C₂H₄(g) + C₄H₈(g) is found to fit the expression ln K = A + B/T + C/T² between 300 K and 600 K, with A = −1.04, B = −1088 K, and C = 1.51 × 10⁵ K². Calculate the standard reaction enthalpy and standard reaction entropy at 400 K.
