4. Recall that when you combined the equations for Reactions (I) and (II) in the second Prelaboratory Question, you reversed the direction of Reaction (I). If a reaction is exothermic in one direction, reversing the direction (products-reactants) changes the sign, but not the magnitude, of 4H. Use your results from question 3 to determine values for AHI, AH2, and AH3, as identified below. Watch signs and be sure to include appropriate units. Space has been left to show your work. Notice that AH, is for the reverse of Reaction (I). Reaction Na (aq) + OH (aq) - NaOH(s) NaOH(s) + HC₂H₂O₂(aq) - →H₂O() + Na'(aq) + C₂H₂O₂ (aq) Na (aq) + OH(aq) + HC₂H₂O₂(aq) - H₂O() + Na (aq) + C₂H₂O₂ (aq) 5. Calculate the sum of AH, and AH₂. Show your work. ΔΗ, = AH₂ ΔΗ, = AH
