![Data Analysis:
1. Make three graphs using the 45°C data:
a) Concentration of [Fe(Phen)3"] vs. time
b) In[Fe(Phen)3"] vs. time
1/[Fe(Phen)3"] vs. time.
+2
c)
Each graph should have a title and axis labels (with units).
2. Fit a straight-line equation through the data for each graph. Display the equation for the
best fit straight line and the correlation constant value (R) on the graph.
3. Construct one graph for the 35°C data using the same type of plot (a, b, or c) that gave a
straight line for the 45°C data. Fit a straight line through the data. Display the equation for
the best fit line and the R value on the graph. Submit all graphs with your data sheet.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F822e3e88-853c-4bca-af7e-eb2a9f17d73a%2F60dfa4f5-c025-4252-b2c4-5166a750ce67%2Fsbkw9tt_processed.jpeg&w=3840&q=75)
