3 cards from this section. Quick, good the night before a test.
What is the Arrhenius equation used for?
Think about reaction rates and temperature.
What is the universal gas constant value in the Arrhenius equation?
It’s a constant used for calculations in chemistry.
What does the Arrhenius equation model?
Recall the topics we've covered on reaction kinetics.
True or False: Higher activation energy means a faster reaction rate.
Consider the meaning of activation energy.
The rate constant for a chemical reaction is known to increase from 3.0 x 10^-5 to 1.2 x 10^-4 s^-1 as the temperature rises from 298 K to 308 K. Using the Arrhenius equation, calculate the activation energy (Ea).
Find the natural log of the ratio of the rate constants and set up the equation to solve for Ea.
A chemical reaction has an activation energy of 50 kJ/mol. How much faster will the reaction be at 350 K compared to 300 K based on the Arrhenius equation?
Set up your calculations carefully, remembering to convert kilojoules to joules for R.
