Question 1

For 2 NO + O2→ 2 NO2, initial rate data are:  

[NO]0 (in M) 0.010 0.010 0.030
[O2]0 (in M) 0.010 0.020 0.020
rate (mM/sec) 2.5 5.0 45.0

The rate law is Rate = k[NO][O2]y:
◦ x = 1, y = 2
◦ x = 2, y = 1
◦ x = 1, y = 1
◦ x = 2, y = 2
◦ x = 0, y = 2

Question 2

For a particular first-order reaction, it takes 24 minutes for the concentration of the reactant to decrease to 25% of its initial value. What is the value for rate constant (in s-1) for the reaction?
◦ 2.0 × 10-4 s-1
◦ 9.6 × 10-4 s-1
◦ 1.2 × 10-2 s-1
◦ 5.8 × 10-2 s-1
