Ammonia (A) diffuses through a stagnant layer of air (B), 1cm thick, at 25 ºC and 1 atm total pressure. The partial pressures of ammonia on the two sides of the air layer are: PA0=0.9 atm and PAl=0.1 atm respectively. Air is none diffusing. Calculate the molar flux of ammonia. DAB= 0.214 cm2 /s

The value

Explanation:

From the question we are told that

     The thickness of the air is

      The temperature is  

     The total pressure is  

      The partial pressure of Ammonia first side is  

      The partial pressure of Ammonia to the second side is

 Rate of flow of ammonia is  

Generally the  molar flux of ammonia is mathematically represented as

Here R is the gas constant with value  

=>

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
