Question 1

It takes 42.0 min for the concentration of a reactant in a first-order reaction to drop from 0.45 M to 0.32 M at 25°C.  How long will it take for the reaction to be 90% complete?
◦ 13.0 min
◦ 86.0 min
◦ 137 min
◦ 222 min
◦ 284 min

Question 2

Nitric oxide gas (NO) reacts with chlorine gas according to the chemical equation given below.
         NO + Cl2→ NOCl
The following initial rates of reaction have been measured for the given reagent concentrations.
Expt. #
Rate (M/hr)
NO (M)
Cl2 (M)
1
1.19
0.50
0.50
2
4.79
1.00
0.50
3
9.59
1.00
1.00
Which of the following is the rate law (rate equation) for this reaction?

◦ rate = k[NO]
◦ rate = k[NO][Cl2]1/2

◦ rate = k[NO][Cl2]
◦ rate = k[NO]2[Cl2]
◦ rate = k[NO]2[Cl2]2
