Question

A student tested the effect of temperature on the decomposition of N2O5. He found that the rate of the reaction at a lower temperature was 4.2 x 10–3 s–1 and the rate at a higher temperature was 1.6 x 101 s–1. What is wrong with the student's data?

A. Nothing. Rate constants are constant for a given reaction temperature, and vary as temperatures change.
B. The rate constant must be less than 1.
C. The rate constant should be the same for each reaction.
D. The rate constant must be greater than 1.

Answer 1

Nothing. Rate constants are constant for a given reaction temperature, and vary as temperatures change.
