Answer:
Q_d=35881 J/mol
So the activation energy is 35881 J/mol.
Explanation:
Consider the following equations:


Solving the above two equation to find the Q_d in term of diffusivity and temperature we will get:

where:
Q_d is the activation energy
D_1 is the diffusivity at T_1
D_2 is the diffusivity at T_2

Q_d=35881 J/mol
So the activation energy is 35881 J/mol.
Explanation:
Protons are the positively charged particles found in an atom.
- A proton is found within the nucleus of an atom.
- Together with the neutron, they make up the nuclear region of an atom.
Protons and neutrons constitutes the bulk mass of the atom.
The mass of a proton is 1.67 x 10⁻²⁷kg
The proton have the same mass as neutrons.
Compared to electrons, it is 1840 times the mass of an electron.

Hey kimalonzo59!
· Calculate specific heat as c = Q / (mΔT). In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/ (kg·K). This is the typical heat capacity of water.
