The diffusion coefficients for species a in metal b are given at two temperatures:
t (°c) d (m2/s) 1030
6.69 × 10-17 1290
6.56× 10-16
(a) determine the value of the activation energy qd (in j/ j/mol
(b) determine the value of m2/s (use scientific notation.)
(c) what is the magnitude of d at 1180°/s .
