lab analysis 2
For K-323 here are the 2 parts needed. Notice that you do not need to submit purpose, procedures or data and observations or conclusions!
1. Title page (just your name and the expt number – will help me identify what I am looking at when I download the submissions and view them).
2. Answers to analysis Q – with the following modifications. You can write answers to Q by hand or in MS-Word or some combination of those. Please rewrite the Q before answering.
For Q 1 and Q 2 show all working so I can see what data numbers you are using.
For Q3 a) and Q 3b):
For each temperature calculate 1/T and ln(rate). Show these calculated values in a table.
Create a plot of ln(rate) vs 1/T. This should be an x-y scatter plot with ln(rate) on the y-axis and 1/T on the x-axis. Remember to have a title, and axis labels on the graph. Use landscape format for any kind of printing that you do with this graph.
Add a best fit straight line and make sure the equation of the line is shown on the graph.
You can make this graph in MS-Excel, or Logger pro or other graphing software you may have. Remember you can download Logger pro from Canvas – you will find it in the modules section under Expt S-201 with instructions on how to install it.
For Q3c) Use the slope of the line from the graph to calculate the activation energy in kilojoules per mol (kJ/mol).
Data
1 room temperature
T i = 21.0 c
Ti = 2:30 min to sec?
Tf = 2:40 min to sec?
Mean?
2) in high temperature
Ti = 40.0 c Tf =28.0 c
ti =2:10 min to sec?
Tf= 2:16 min to sec¿
Mean?
3) In low temperature
Ti= 5.30 c Tf= 10.6 c
Ti= 3:40 min to sec?
Tf= 3:51 min to sec?
Mean?
