ARate to the temperature of the reaction
BRate to the activation energy of a step
CRate constant to the number of collisions
DConcentration of a reactant to elapsed time
Answer & Solution
Correct answer: D. Concentration of a reactant to elapsed time
1. An ordinary rate law links rate to concentration at one instant.
2. Integrating it with respect to time gives a second form of the same law.
3. That second form links the concentration of a reactant to the time that has elapsed.
4. This is what lets you work out how much reactant is left after a given time.
