3. Consider the following set of reactions: Overall reaction: CH4e) + NH3(8) → HCN8) + 3 H2e) AHoverall = ??? kJ Reaction 1: N2e) + 3 H2g) → 2 NH3(8) Reaction 2: Cs) + 2 H2(e) → CH4(e) Reaction 3: H2e) + 2 Cs) + N2(g) 2 HCN(e) AH, = -91.8 kJ AH2 = -74.9 kJ AH3 = +270.3 kJ a. What must be done to Reaction 1 to get NH3 on the reactant side? What is the resulting value of AH,? (Do not forget the unit) b. What must be done to Reaction 2 to get CH4 on the reactant side? What is the resulting value of AH2? (Do not forget the unit) C. What must be done to Reaction 3 to get one mole of HCN on the product side? What is the resulting value of AH3? (Do not forget the unit) d. Calculate the AHoverall by doing a summation of the modified reactions 1-3. (Do not forget the unit)
