Abstract

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} = k_nuc{[NH₃][HCl]}ⁿ, where R {N} represents particle production rate, n = 2.7 and k_nuc = 1 × 10^{-(76 ± 15)} cm^13.2s^-1. Particle growth was attributed to the condensation reaction. Condensation rate coefficient was calculated from the equation: R{NH₄Cl(s)} = k_con[NH₃][HCl][N], where RNH₄Cl(s) is the rate of NH₄Cl formation in the solid phase and the rate coefficient for condensation, k_con, was found to be 7 × 10^-26 cm⁶ s^-1.
