6. (20 points) Given the data in Table 4, determine the rate law for the reaction. NH(aq) + NO (aq) → N2(g) + 2H20(1) Experiment | |NH||(M) [NO](M) Rate x 10-* (M/s) 1 0.2500 0.2500 1.25 2 0.5000 0.2500 2.50 3 0.2500 0.1250 0.625 0 N Table 4: 7. The mechanism for the decomposition of hydrogen peroxide in the presence of I-aq) is proposed to be: Step 1: H2O2(aq) + F(aq) → H20(1)+ or (aq)(slow) Step 2: H2O2(aq) + or (aq) + H2O(l) + O2(g) + (aq) (fast) (1) (5 points) What is the overall reaction? (II) (10 points) What is the rate law for this reaction?
(III) (5 points) What is the molecularity of Step 1? (IV) (5 points) Identify and list any catalyst(s) and intermediate(s). If there are none then write N/A 8. (15 points (bonus)) Derive the Henderson-Hasselbalch equation from the acid ionization constant expression 9.
