QI/ Ammonia gas (A) is diffusing through stagnant N2 (B) under steady-state conditions. The total pressure 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 (y2%). The diffusivity coefficient of ammonia in nitrogen at above conditions is 2.293*10 m/s: How much would the flux of ammonia and the mass transfer coefficient change at the following conditions: 1- When the total pressure is increased by three times at constant temperature. 2- When temperature is decreased to 100 K at constant pressure. 3- When the temperature is increased to 350 K and the pressure decreased to half
