Which of the following statements is true?
A) The activation energy always increases as temperature rises.
B) The activation energy always decreases as temperature rises.
C) The rate constant always decreases as temperature rises.
D) The rate constant always increases as temperature rises.
E) The rate constant always increases as the activation energy increases.3.
Suppose a reaction has the following rate law: rate = k[A][B]1/3 Which of the following can be concluded about the reaction?
A) The reaction mechanism has multiple steps.
B) Three molecules of A react with every molecule of B.
C) Three molecules of B react with every molecule of A.
D) Molecule A reacts at three times the rate of Molecule B.4.
What is the rate law for the reaction A + B + C ? D if the following data was collected?
Experiment No. [A] (M) [B] (M) [C] (M) Rate (M/min)
1 0.1 0.2 0.3 230
2 0.2 0.4 0.3 460
3 0.3 0.6 0.6 620
4 0.4 0.2 0.3 920
A) rate = k[A][B][C]
B) rate = k[A]2[B][C]2
C) rate = k[A][C]
D) rate = k[A][C]3
E) rate = k[A]2[C]2
