Question
I need the answer quickly
Transcribed Image Text:QIU Ammonia gs (A) is difisingthough shgnat N (B) under stady-sate
conditions. The total presue is 1.013-10 Pa)and 298 K. The concentration of
NH, at one point is (yl) mole fraction . At the other point of 20 mm away, its
concentration is (92%). The difsvty coeficiet of amonia in nirogen at
above conditions is 293910° mis:
How much would the flux of ammonia and the masstransfer coeficient change at
the folowing condtion:
|- When the total presure is icreased by three imes at constant temperature.
2- When temperatue is decreased to 100 K at constan presure.
3- When the temperatue is increased to 350 K and the presure dereased to a
half
