Calculate the value of the diffusion coefficient D (in m2/s) at 547°C for the diffusion of some species in a metal; assume that the values of D0 and Qd are 5.6 × 10-5 m2/s and 177 kJ/mol, respectively.
1 answer:
Answer : The value of diffusion coefficient is,
Explanation :
Formula used :
where,
D = diffusion coefficient = ?
=
=
R = gas constant = 8.314 J/mol.K
T = temperature =
Now put all the given values in the above formula, we get:
Thus, the value of diffusion coefficient is,

Answer:
v = 16 m/s
Explanation:
Given that,
Distance, d = 400 m
Time taken, t = 25 s
We need to find the speed of the horse. Speed is equal to distance covered divided by time taken. So,
So, the speed of the horse is 16 m/s.
