What is the rate law for the following mechanism? CH3COOC2H5 + ...

[kamilo84]

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 E_a = 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]
