The reaction 2A + 5B products is first order in A and first ...

[RYAN BANYAN]

Question 1

The reactants A and B are mixed, and the reaction is timed until a color change occurs. The data are as follows:

[A]	[B]	Time (s)
0.100	0.140	25
0.050	0.140	25
0.100	0.070	100

The order of the reaction in terms of B is

◦ 2.
◦ 1/2.
◦ 0.
◦ –1/2.
◦ 1.

Question 2

The reaction 2A + 5B → products is first order in A and first order in B. What is the rate law for this reaction?

◦ rate = k[A]²[B]⁵
◦ rate = k[A]¹[B]²
◦ rate =k[A]¹[B]¹
◦ rate = k[A]⁵[B]²
◦ rate = k[A]^2/7[B]^5/7
