To calculate the enthalpy change of isomerization for the conversion of cis-but-2-ene to trans-but-2-ene, we can use the following equation:H_isomerization = H_f trans-but-2-ene - H_f cis-but-2-ene Where H_isomerization is the enthalpy change of isomerization, H_f trans-but-2-ene is the enthalpy of formation of trans-but-2-ene, and H_f cis-but-2-ene is the enthalpy of formation of cis-but-2-ene.Plugging in the given values:H_isomerization = -28.6 kJ/mol - -24.7 kJ/mol H_isomerization = -3.9 kJ/molThe enthalpy change of isomerization for the conversion of cis-but-2-ene to trans-but-2-ene is -3.9 kJ/mol.
