![Q1. Three parameters affect the absorbance of a sample. Which one is the focus of
this experiment?
O the molar absorptivity coefficient
O concentration of the absorbing substance
O thickness of the sample containing the absorbing substance
Q3. In experimental Procedure, Part A.1.: For preparing a set of standard solutions of
FeNCS, the equilibrium molar concentration of FeNCS2* is assumed to equal the
initial molar concentration of the SCN in the reaction mixture. Why is this assumption
valid?
O The high concentration of the SCN
ion ensures that the reaction is favored to the right
O The low concentration of the iron ion ensures that the reaction is favored to go to the right
O This reaction will not reach equilibrium
O The high concentration of the iron ion ensures that the reaction is favored to go to the right](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe70c8743-1c47-4a3c-a696-b5ed8cd8e2f3%2F0a28de6b-1fdf-41d3-8689-a46badcdc80e%2Fuzj4r1j_processed.jpeg&w=3840&q=75)
