# Calculation Of Activation Energy And Preexponential Factor Of Reaction

Question

The rate constant of a reaction increases by 23%, when the temperature is increased from 20° to 27°C.

(a) What is the activation energy of the reaction.

The rate constant of a first-order reaction was measured as a function of temperature and recorded data are shown in the table. Calculate the activation energy and the pre-exponential factor for A.

 T/°C 0 10 20 30 40 50 60 70 80 90 100 k/s-1 1002 1509 2120 3201 4498 6101 8261 12002 16308 22911 30200

Information

R = 8.3144 J mol-1 K-1

Temp/K = Temp/°C + 273.16

Summary

The question belongs to Chemistry and it discusses about calculation of activation energy and pre-exponential factor for the reaction.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
