Strong Similarity

Using the ECR-technique the capture of thermal-energy free electrons was investigated by the molecules HNO3 and ClNO3. The following rate constants at room temperature were obtained: k(HNO3) =(1.4 ±0.7)· 10-8 cm3 sec-1 ;k (ClNO3) = (3.9 ± 1.2)· 10-9 cm3 sec-1 .An apparent activation energy of AE = (1.6 ± 0.5) kcal · mol-1 was found for the reaction with ClNO3. From the energy dependences of the both reactions together with thermodynamic considerations it is suggested that electron capture by ClNO3 occurs via dissociative attachment whereas with HNO3 a negative parent ion can be formed. Strong similarity is pointed out to exist between HONO2 and ClONO2 towards capture of electrons and the reaction with O2- respectively.
