Suppose an "excited" gas-phase molecule is generated by some means (e.g., an electron in the molecule might be ejected into an excited state by means of a laser). However, the excited molecule is "quenched" the instant it collides with another molecule. a. What will be the average lifetime of the excited molecule at room temperature and pressures of 1 atm and 10^-9 atm? b. For both pressures, estimate how far the molecules will have traveled before being quenched.
