An electronically excited state of Hg can be quenched by N, according to Hg* (g) + Nz
Question:
Hg* (g) + Nz (g, V = 0) -7 Hg (g) + N, (g, v = 1) in which energy transfer from Hg* excites Nz vibrationally. Fluorescence lifetime measurements of samples of Hg with and without Nz present are summarized below (T= 300 K):
You may assume that all gases behave ideally. Determine the rate constant for the energy transfer process.
