Question

The data for the reaction A + B $\rightarrow$ C is

Exp.	[A]0	[B]0	Initialrate
1 2 3 4	0.012 0.024 0.012 0.024	0.035 0.035 0.070 0.070	0.10 0.80 0.10 0.80

• A. r = k [B]3
• B. r = k [A]3
• C. r = k [A] [B]4
• D. r = k [A]2 [B]2 .

Answer 1

Answer: (B)

r = k $A$3

Answer 2

$x = \frac{\log\left( \frac{r_{1}}{r_{2}} \right)}{\log\left( \frac{a_{1}}{a_{2}} \right)} = \frac{\log\frac{0.1}{0.1}}{\log\left( \frac{0.012}{0.024} \right)} = \frac{\log\left( \frac{1}{8} \right)}{\log\left( \frac{1}{2} \right)}$$$x = 3$$

}{y = 0}$$
