Interpretation Introduction
Interpretation:
The factor that determines the line widths for absorption lines and atomic emission also the widths of these lines should be determined.
Concept introduction:
Spectral lines are lines which help in identifying the atoms and molecules. These are a result of absorption or emission of light in a comparatively narrower frequency range compared to the frequencies nearby.

The decomposition of dinitrogen pentoxide according to the equation:
50°C
2 N2O5(g)
4 NO2(g) + O2(g)
follows first-order kinetics with a rate constant of 0.0065 s-1. If the initial
concentration of N2O5 is 0.275 M, determine:
the final concentration of N2O5 after 180 seconds.
...
Don't used hand raiting
CS2(g) →CS(g) + S(g)
