Learning Goal: To understand how to use Hess's law to find the enthalpy of an overall reaction. Constanta I Eans. Tatle Part C The change in enthalpy, AH, is the heat absorbed or produced during any reaction at constant pressure. Hess's law states that AH for an overall reaction is the sum of the AH values for the individual reactions. For example, if we wanted to know the enthalpy change for the reaction What is the enthalpy for the following reaction? overall: C2H4 + H20- C2H,OH Express your answer numerically in kilojoules per mole. 3Mn +302-3MNO2 • View Available Hint(s) we could calculate it using the enthalpy values for the following individual steps: Step 1: 4Al + 302-2Al2O3 ΔΗ- kJ/mol Step 2: 3Mn + 2Al2O3+3MNO2 + 4A1 Overall: 3Mn + 302-3MNO2 Submit Previous Answers If the enthalpy change is -3352 kJ/mol for step 1 and 1792 kJ/mol for step 2, then the enthalpy change for the overall reaction is calculated as follows: X Incorrect; Try Again; 24 attempts remaining ΔΗ- -3352+ 1792…
