Question

A     sphere     of     naphthalene     having     radius     of     4    mm    is     suspended    in    a    large    
volume    of    still    air at    315    K    and    1    atm.    The    partial    pressure    at    the    surface    
of     naphthalene     at     315     K     is     45     Pa.     Assume     dilute     gas     phase.     DAB of    
naphthalene     is     6.3x10-6 m2/s.     Calculate     the     evaporation     rate     of    
naphthalene.    (R=    8314    m3.Pa/kmol.K.;    1    atm=1.013x105 Pa.)
