The following reaction: A' (a) + B (ag + C (an)→ G* (ae) +2 H ) AH = -250 kJ There are two proposed mechanism: Mechanism 1 A' () + B aa) AB' a) + D (a) Step 1 AB" (a) (fast) + E (a) + Hm → G' sae) + H ) + D² (n) Step 2 (slow) Step 3 E (agi+ C (a) (fast) Mechanism 2: Step 1 AB' (a) A' (an) + B (ag) AB' (a) + C ja) (fast) Step 2 + G' (a) + 2 H() (slow) The reactions was determined to have the following rate law: r= k[A'][B] a) Which of the two proposed mechanisms is valid? Explain. b) List any reaction intermediates: catalysts: c) What is a rate determining step? d) If the activation energy for the overall forward reaction is 150 kJ, sketch the potential energy diagram for the above reaction; showing the overall reaction, the reaction mechanism, labelling the AHu, AHy, Eapu, Eag, reaction intermediates, and activated complex. rvs fwd drvs/

How would you solve c?   Transcribed Image Text:Temperature (°C) AN A student conducts an experiment to determine the value of for the dissolution of Na₂C₂H₂O₂ (s). The student dissolves 10.0 g of Na₂C₂H₂O₂ (s) in room-temperature water in a beaker and measures the temperature over time. The data are given in the graph above. 24- 22- 20 18 16 14 12- 10 Time (a) The student touches the side of the beaker after the dissolution has occurred and observes that it is cold. What experimental evidence is consistent with the student's observation? (b) Is the dissolution of endothermic or exothermic? Justify your answer in terms of the flow of energy between the system and surroundings. in kJ/mol. (c) The student calculated the energy change for the dissolution to be 4600 J. Based on this value, calculate AH soln
