1. The pyrolysis of ethyl nitrate (C2H5NO3,A) to generate formaldehyde (HCHO, B), methyl nitrite (CH3NO2,D), acetaldehyde (CH3CHO,E), ethanol (C2H5OH,F) and NO2 occurs as per the mechanism [1,2] (1) A(M1)k1C2H5O(M2)+NO2(M3) (2) C2H5Ok2CH3(M4)+B(M5) (3) A+CH3k3D(M6)+C2H5O (4) 2C2H5Ok4E(M7)+F(M8). (c). Apply PSSH for C2H5O and CH3 to obtain expressions for concentrations of the two radical species. Establish that RE=RF=21RNO2,RB=RD,RA=(RD+2RE). Derive expression for RA
