To find how fast molecules or particles of gases move at a particular temperature, the root mean square speed is calculated.
Root mean square speed of a gas is calculated by using the formula;

$Root mean square=\sqrt{ \frac{3RT}{M}$

Where R is the molar gas constant, T is the temperature and M is the molar mass of gas in Kg.

<h3>Step 1: Root mean square speed from O₂</h3>

Molar mass of Oxygen is 32.0 g/mol or 0.032 kg/mol

Temperature = 65 degrees Celsius or 338 K

Molar gas constant = 8.3145 J/k.mol

$Root mean square speed = \sqrt\frac{(3)(8.3145)(338K)}{0.032}$

$= 513.289 m/s$

<h3>Step 2: Root mean square speed of UF₆ </h3>

The molar mass of UF₆ is 352 g/mol or 0.352 kg/mol

$Root mean square speed = \sqrt\frac{(3)(8.3145)(338K)}{0.352}$

$= 154.762m/s$

Therefore; the root mean square speeds of O₂ and UF₆ is 513m/s and 155 m/s respectively.

The reactants are the substances on the left side, which react and give the products on the right side.
The reactants are Fe and O.
The product is Fe2O3.
The arrow to the right means that the reaction is going in only one direction — the only reaction happening at the moment is that Fe and O are making Fe2O3.
(s) means the substance is in the solid state, and (g) means in a gaseous state (or the substance is a gas in that reaction).
