<u>Answer:</u> The temperature of the system will be 1622 K
<u>Explanation:</u>
The equation relating the pre-exponential factor and activation energy follows:

where,
D = diffusion coefficient = 
= pre-exponential constant = 
= activation energy of iron in cobalt = 273,300 J/mol
R = Gas constant = 8.314 J/mol.K
T = temperature = ?
Putting values in above equation, we get:

Hence, the temperature of the system will be 1622 K

Answer:
The boiling point of water, or any liquid, varies according to the surrounding atmospheric pressure. ... With that much less pressure, you don't need to apply as much heat to push vapor pressure beyond the surrounding atmospheric pressure – in other words, water boils at a lower temperature.
Answer:
CO2
Explanation:
it's the simplest whole number ratio of atoms of each element in the compound.
