Question 9 4 pts Exactly 1.100 g of CO2(g) was introduced into a 1.00-L flask that already contained some O2 gas. The flask was warmed to 100 °C and the total pressure was found to be 815 mmHg. No chemical reaction occurred between CO2 and 02. Calculate the mass of Oz in the flask. 1.12 g 02 O 0.160 g 02 O 0.754 g 02 O 0.820 g 02 O 0.321 g 02 1.5 pts Question 10...

All student groups will receive data for the hypothetical reaction aAlE) products where a is a numeric variable and A is a chemical variable. The reaction therefore has the form of a decomposition reaction, in which a single substance forms one or more new substances. For consistency, all concentrations start out at 1.000...

Data needed to be calculated is in highlighted in green boxes.
And I highlighted in red an equation (not sure if thats what you
use to calculate it) And ignore the lab instructions on completeing
a graph!! I already know how to do that in excel, just curious how
Ln (relative rate) and 1/T in K^-1 is calculated by hand*
