Question
Consider these reactions, where M represents a generic metal. 1. 2 M(s) + 6 HCI(aq) → 2 MCI, (aq) + 3 H, (g) AH1 = -666.0 kJ 2. HCI(g) - → HCl(aq) 3. H, (g) + Cl,(g)· MCI, (aq) AH, = -74.8 kJ 2 HCI(g) AH3 = -1845.0 kJ 4. MCI, (s) AH = -382.0 kJ Use the information to determine the enthalpy of the reaction 2 M(s) + 3 Cl, (g) –→ 2 MCI, (s) ΔΗ STRATEGY 1. Identify how each equation should be manipulated. 2. Calculate the new individual enthalpies. 3. Calculate the overall enthalpy by summing the individual enthalpies. Step 1: The methods by which equations 1-4 are manipulated so they will add up to the goal reaction are shown. Step 2: Identify how each of the individual enthalpies are affected when the equations are reversed or multiplied by a factor.

Step 2: Identify how each of the individual enthalpies are affected when the equations are reversed or multiplied by a factor. Equation 1 is in the forward direction multiplied by a factor of 1. Enthalpy of equation 1 adjusted for direction and factor: kJ Equation 2 is in the forward direction multiplied by a factor of 6. Enthalpy of equation 2 adjusted for direction and factor: kJ Equation 3 is in the forward direction multiplied by a factor of 3. Enthalpy of equation 3 adjusted for direction and factor: kJ Equation 4 is in the reverse direction multiplied by a factor of 2. Enthalpy of equation 4 adjusted for direction and factor: kJ
