Question 1
What is the activation energy for a reaction that has a rate constant of 5.68 × 10
-8 s
-1 at 298 K and 1.73 × 10
-5 s
-1 at 348 K?
◦ 70.0 kJ mol
-1◦ 41.4 kJ mol
-1◦ 66.2 kJ mol
-1◦ 19.4 kJ mol
-1◦ 98.6 kJ mol
-1Question 2
Given the following proposed mechanism, predict the rate law for the overall reaction.
2NO2 + Cl2 → 2NO2Cl | (overall reaction) |
Mechanism
NO2 + Cl2 → NO2Cl + Cl | slow |
