<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
<u>Answer: </u>The chemical formula for Palladium(IV) sulfate is 
<u>Explanation:</u>
Palladium is the 46th element of the periodic table which has an oxidation state of +4 (because it is a metal and will form positive ion) and sulfate is the polyatomic ion having a charge of -2 with formula 
So, to write the formula of the compound, we do criss cross method in which oxidation state of each element or ion is given to the other combining atom which results into the formation of a neutral compound.
The chemical formula of the compound is 
The image is given below.
The end pH will be 7 if the acid and base were added in the correct amounts in relation to each other.
general formula:
HA+BOH⇒H₂O+AB (AB is the salt produced from the anion in the acid and cation in the base)
