5. Compare the values of K_eq for each of the five solutions:
a. Are any of the values outside the sample standard deviation for the set?
b. Does the value of the equilibrium constant change when the concentration of either the reactants or products is altered? Why or why not? Explain this based on your calculations of K_eq.
c. What caused variation (three reasons) in your values of K_eq?
