Chemical Kinetics - Activation Energy and gr

Click For Summary
SUMMARY

The discussion focuses on solving problems from a chemical kinetics problem set, specifically problems 12 and 13. The value of the rate constant (k) for problem 12 is established as 1.54 x 10^-4. Problem 13 requires understanding the integrated rate laws for zero, first, and second-order reactions, which are essential for determining the rate law and rate constant. Additionally, the Arrhenius equation is necessary for calculating the rate constant at 650K for problem 14.

PREREQUISITES
  • Understanding of chemical kinetics concepts, specifically rate laws.
  • Familiarity with integrated rate laws for zero, first, and second-order reactions.
  • Knowledge of the Arrhenius equation and its application in calculating rate constants.
  • Basic problem-solving skills in chemistry, particularly in kinetics.
NEXT STEPS
  • Study the integrated rate laws for zero, first, and second-order reactions.
  • Learn how to apply the Arrhenius equation for temperature-dependent rate constants.
  • Practice solving chemical kinetics problems similar to those in the Harvard problem set.
  • Explore resources on determining rate laws from experimental data.
USEFUL FOR

Chemistry students, educators, and anyone involved in chemical kinetics who seeks to deepen their understanding of activation energy and rate laws.

The problems are Number 12 and 13 on this link
http://isites.harvard.edu/fs/docs/icb.topic1096438.files/PS4.pdf

I have the value of k for sum number 12, it is 1.54*10^-4.

Im completely stuck with number 13 cos I'm unfamiliar with that concept and it kinda went over my head in lecture this morning.

If anyone wants to help with 14, it would be appreciated :D

The problem set is due in like 10 hours, so no pressure xD
 
Physics news on Phys.org
the integrated rate law for 0th,1st,2nd order might help for problem 13.
for q.14 use first two data to find the rate law and rate constant.
then using arrhenious equation and the third data find rate constant at 650K.
use the integrated form of rate law to find the required time.
