  1. Describe a scenario where a researcher could use a Goodness of Fit Test to answer a research question. Fully describe the scenario and the variables involved and explain the rationale for your answer. Why is that test appropriate to use?
  2. Describe a scenario where a researcher could use a Test for Independence to answer a research question. Fully describe the scenario and the variables involved and explain the rationale for your answer. Why is that test appropriate to use?
  3. The Goodness of Fit Test and Test for Independence both use the same formula to calculate chi-square. Why? I.e., explain the logic of the test. (3 points)
  4. Compare the Goodness of Fit Test and the Test for Independence in terms of the number of variables and levels of those that can be compared. In what ways are they similar or different?
  5. Describe how the Test for Independence and correlation are similar yet different.

(a) Consider the temperature dependent heat capacity of O2(g) given in the Resource
section of your textbook (29.355J/Kmol). What is the heat absorbed at constant pressure when 1 mole
of O2(g) is heated from 0o C to 500oC? (Hint: Integrate!)

(b) Construct a plot of Cp,m (for O2(g)) vs. T and plot it between 0 and 500
oC. What is the % error if you had used a temperature-independent heat capacity for part (a)?

From information in the “Data section” of your textbook, calculate the standard

Gibbs free energy and the equilibrium constant at (a) 25°C and (b) 50°C for the reaction

CH4(g) + 3 Cl2(g) <--> CHCl3(l) + 3 HCl (g).

Assume that the reactionenthalpy isindependent of temperature.

ΔG°f (CHCl3, l) =-­71.8 kJ/mol, ΔH°f(CHCl3, l) =‐132.2 kJ/mol

Which extra DATA can i provide from the textbook. What values should I look for?
