Question 1

The following data were obtained at 25°C:

[A]₀	[B]₀	[C]₀	Rate
0.1	0.2	0.3	0.063
0.3	0.4	0.2	0.084
0.6	0.4	0.2	0.168
0.3	0.4	0.1	0.021
0.6	0.2	0.2	0.168

What is the correct rate law?

◦ Rate = k[A][B][C]
◦ Rate = k[A][B][C]²

◦ Rate = k[A][C]
◦ Rate = k[A]³[B]²[C]
◦ Rate = k[A][C]²

Question 2

The following data were obtained for the reaction 2A + B → C where rate = Δ[C]/Δt

[A](M)

[B](M)

Initial Rate (M/s)

0.100	0.0500	2.13 × 10^–4
0.200	0.0500	1.70 × 10^–2
0.400	0.100	1.36 × 10^–1

What is the value of the rate constant?

◦ 2.13
◦ 0.213
◦ 0.426
◦ 1.70
◦ None of these are correct.
