Explanation:
Using Beer-Lambert's law :
Formula used :
where,
A = absorbance of solution
c = concentration of solution
l = length of the cell
= molar absorptivity of this solution
According to question:
A = (C) : absorbance measured by the spectrometer
c = (B) : concentration, in mol/L, of the stock solution from which the sample was made
l = (A): pathlength of light through the cell
ε = (D) : molar absorptivity, a constant unique to that substance at that wavelength
Answer: Option C is correct.
Explanation: Average kinetic energy is directly proportional to the absolute temperature. Higher the temperature means higher the kinetic energy.
Average kinetic energy is given by:
Where, k = Boltzman constant
T = Temperature
We are given different temperatures, so to compare they all should have the same units.
a) 298K
b) 267K
c) 27°C = 273+27 = 300K
d) 12°C = 273+12 = 285K
Looking at the temperature values, C part will have the highest average kinetic energy.
