Question 1

The following questions refer to the reaction shown below:

			Initial Rate of
	Initial [A]	Initial [B]	Disappearance of A
Experiment	(mol/L)	(mol/L)	(mol/L·s)
1	0.16	0.15	0.08
2	0.16	0.30	0.30
3	0.08	0.30	0.08

What is the order of this reaction?

Question 2

The kinetics of the reaction A + 3B → C + 2D were studied and the following results obtained, where the rate law is:

–

= k[A]ⁿ[B]^m

For a run where [A]₀ = 1.0 × 10^–3M and [B]₀ = 5.0 M, a plot of ln [A] versus t was found to give a straight line with slope = –5.0 × 10^–2 s^–1.
For a run where [A]₀ = 1.0 × 10^–3M and [B]₀ = 10.0 M, a plot of ln [A] versus t was found to give a straight line with slope = –7.1 × 10^–2 s^–1.

Calculate the value of k (ignore units).
