1. Introduction
Ammonia (NH3) is one of the most familiar compounds of nitrogen and hydrogen as well as one of the world's most valuable industrial and agricultural chemicals. Ammonia is used throughout the industrial world as a valuable fertilizer.
Ammonia and its compounds, primarily ammonium nitrate and other ammonium salts, replenish nitrogen in depleted soils. This greatly increases y
Diffusion
물질의 확산은 1855년 Adolf Fick에 의해 유도된 Fick’s Law 를 따르며 이는 다음과 같이 표현된다.
J= -D ∂C/∂x
∂C/∂x= Concentration gradient in the x-direction [M/s]
J=Diffusion flux across unit are at right angles to the x-direction [ mol/(s∙cm^2 )]
D=Diffusion constant [ cm^2/s]
