I need the answer as soon as possible
P. A sphere of naphthalene (C10Hs) having a radius of 4 mm is suspended in a large volume of still air at 320 K and 101.325 kPa. The vapor pressure at this temperature is 0.61 mmHg and the diffusivity of naphthalene in air at 320 K is 0.0256 m2/hr, calculate: 1.- The rate of evaporation of naphthalene from the surface. 2- The partial pressure of naphthalene at a distance 30 mm from the surface of the naphthalene sphere. 5
