Question 1

What is the rate constant at 305 K for the reaction:

2 N2O5→ 2 N2O4 + O2,  

if k = 3.46 × 10-5 s-1 at 298 K and Ea = 106 kJ/mol?
◦ 2.4 × 10-5 s-1
◦ 4.8 × 10-5 s-1
◦ 6.0 × 10-5 s-1
◦ 1.2 × 10-5 s-1
◦ 9.2 × 10-5 s-1

Question 2

What is the rate law for the following mechanism?

CH3COOC2H5 + H2O → CH3COOC2H6+ + OH- (slow)
CH3COOC2H6+→ CH3COOH + C2H5+ (fast)
C2H5+ + OH-→ C2H5OH (fast)

◦ Rate = k[CH3COOC2H5][H2O]2
◦ Rate = k[C2H5OH]
◦ Rate = k[CH3COOH]
◦ Rate = k[CH3COOC2H5]
◦ Rate = k[CH3COOC2H5][H2O]

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
