Standard reaction Gibbs free energy for the isomerization of cis-2-pentene to trans-2-pentene at 400 K is -4.67 kJ/mol. Calculate the equilibrium constant for the isomerization process.
For the reaction:
C5H10(4) + 3O2(g) -> 2CO2(g) + 3H2O(g), the standard reaction internal energy is -1483 kJ/mol at 298 K. Calculate the standard reaction enthalpy.
