A general reaction written as A + 2B ® C + 2D is studied and yields the following data:

		[A] 0	[B] 0	Initial D[C]/D t
		0.150 M	0.150 M	8.00 ´ 10 –3 mol/L·s
		0.150 M	0.300 M	1.60 ´ 10 –2 mol/L·s
		0.300 M	0.150 M	3.20 ´ 10 –2 mol/L·s

1. What is the numerical value of the rate constant?

2. Determine the initial rate of B consumption (D[B]/D t ) for the first trial?

3. For a first order reaction with a rate constant k = 3.13 x 10 ² s ^-1 , how long does it take for the concentration of the only reactant to become 40% of the original amount?
