Multiple Choice
Fluctuations in flame temperature affect the reproducibility of atomic emission experiments more so than atomic absorbance experiments.Which of the following statements explain this phenomenon?
I As temperature increases there is an increase in emission intensity resulting from an increase in the excited state population;the apparent concentration is greater than the actual concentration.
II As temperature decreases there is a decrease in emission intensity resulting from an increase in the excited state population;the apparent concentration is greater than the actual concentration.
III As temperature increases there is a decrease in emission intensity resulting from a decrease in the excited state population;the apparent concentration is less than the actual concentration.
IV As temperature decreases there is a decrease in emission intensity resulting from a decrease in the excited state population;the apparent concentration is less than the actual concentration.
A) II and III
B) I and IV
C) I and III
D) II and IV
