Use the following data to answer Questions 25 and 26:

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

[A]₀	[B]₀	Initial D[C]/Dt
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

25. What is the numerical value of the rate constant?
26. Determine the initial rate of B consumption (D[B]/Dt) for the first trial?

27. For a first order reaction with a rate constant k = 3.13 x 10² s^-1, how long does it take for the concentration of the only reactant to become 40% of the original amount?
