N2 - Particle formation in the reaction of NH3 and HCl under 1 atm of N2 and at 25°C was studied in a flow reactor. The critical concentration below which no particle can be formed was found to be 3.5 × 1014 molecule cm-3 for [NH3] = [HCl]. Above this concentration, gas-particle conversion percentage increases rapidly to approach 100%. Particle nucleation was found to behave according to the rate equation R{N} = knuc{[NH3][HCl]}n, where R {N} represents particle production rate, n = 2.7 and knuc = 1 × 10-(76 ± 15) cm13.2s-1. Particle growth was attributed to the condensation reaction. Condensation rate coefficient was calculated from the equation: R{NH4Cl(s)} = kcon[NH3][HCl][N], where RNH4Cl(s) is the rate of NH4Cl formation in the solid phase and the rate coefficient for condensation, kcon, was found to be 7 × 10-26 cm6 s-1.
