Q66 · CSIR NET Chemistry, June 2012
Paper: CSIR NET June 2012 · Subject: Physical Chemistry · Chapter: Chemical Kinetics · Topic: Chemical Kinetics – General · Marks: 2 · Difficulty: Medium
Using cuvettes of 0.5 cm path length, a $10^{-4}$ M solution of a chromophore shows 50% transmittance at certain wave length. The molar extinction coefficient of the chromophore at this wave length is (log 2 = 0.301)
(a)$1500\,\mathrm{M^{-1}cm^{-1}}$
(b)$3010\,\mathrm{M^{-1}cm^{-1}}$
(c)$5000\,\mathrm{M^{-1}cm^{-1}}$
(d)$6020\,\mathrm{M^{-1}cm^{-1}}$
