Question

11. Below are 2 possible reaction mechanisms (pathways) for the reaction Mechanism 1 No, + 03 → No, (fast) NOs + NOs → N20s + 5/202 (slow) Mechanism 2 NO2 + 03 → NO3 + 02 (slow) No, + NO2 → N20s (fast) If the reaction rate law is found to be: rate = k[NO21 Which mechanism is consistent with this rate law (1 or 2) What is/are the intermediate/s for Mechanism 1? What is/are the intermediate/s for Mechanism 2? what is the molecularity of each reaction in Mechanism 1? 12. Draw a potential energy diagram below that shows the following: Forward Activation Energy (E,) - 100kJ/mol Enthalpy of reaction (AH)- -100 k/mol Energy per mole -show the Ea and ΔH on the graph the graph should be roughly to scale Progress of reaction → C. d. Describe and draw on the graph how the resulting potential-energy curve might look if a catalyst was added to the reaction 13. Which of the following compounds has the greater lattice energy (circle one)(2 pts). NaCi KBr 14. Which of the following ions has the greater hydration energy (circle one)? Mg A 15. Which of the following is greater in an endothermic solution process (circle one)? Lattice Energy Hydration Energy
