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
