Procedure for Using Hess's Law 23 of 36 Now consider the following set of reactions 1. СР+ 102.-CO2 , aH -283 kJ/mol how to use Hess's law to find the enthalpy of an overall reaction The change in ornabyAH, s the heat absorbed or produced during any reaction at constant reactor is the sum of the ÎÎ values for the know the enthalpy change for the reaction law statos that AH for an overal overall: C+CO However, one of them must be reversed. Which one? Step 1: 4A1 +30,-+2Al 0 Step 2: 3Mn + 2Also,-+3MnO, +4A1 Overal: 3Mn+30-3MnO If the enthalpy change is-3352 kJ/mol for step reaction 1: CO02CO reaction 2: C+0,+co follows: Correct the sum of the ÎÎ values for any set of the desired product from the starting materials Part B What is the enthalpy for reaction 1 reversed? reaction 1 reversed: CO,- co+102 MacBook Pro Procedure for Using Hess's Law 23 of 36> reaction 1: CO02+CO2 reaction 2: C+o,+co, Constants 1 Peciodic Table Learning Goal: To enthalpy of an overall reaction. Previous Answer during any reaction at constant pressure, Hess's law states that ÎH foran Correct is the sum of the AH values for the reactions. For example, if we wanted to we could What is the enthalpy for reaction 1 reversed? reaction 1 reversed CO CO0 Step 1: 4Al +302+2Al2Os Step 2: 3Mn+2A120s+3MnO2+4A Overall 3Afn +302â3M102 1 and 1792 k.J/mol for step 2, then the enthalpy change for the overall reaction is follows as kJ/mol AH--3352+17921560 kJ/mol It is also important to note that the change in independent of path. In other words, the sum of the Submit Request Answe H values for any set of reactions that produce the desired product from the starting materials Part C Complete previous part s) MacBook Pro Show transcribed image text
