What is the activation energy (q) for a vacancy formation if 10 moles of a metal have 2.3 x 10^13 vacancies at 425°c?

Explanation:

Using the expression shown below as:

Where,

is the number of vacancies

N is the number of defective sites

k is Boltzmann's constant =

is the activation energy

T is the temperature

Given that:

N = 10 moles

1 mole =

So,

N =

Temperature = 425°C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T = (425 + 273.15) K = 698.15 K  

T = 698.15 K

Applying the values as:

i lost in getting someone back.

i learned that people are really two-faced and no matter how angelic someone appears they always have a devil side and that you cant trust anyone anymore no matter how dear they are to you.
