Answer:
True
Explanation:
True. Since in an elementary step , the reaction procedes by collision of the atoms of reactants involved and since the rate of collision is proportional to the concentration of each atom that participates in the elementary step , the exponents in the rate law of the elementary step always coincides with the coefficients that correspond to that reaction ( regardless if is unimolecular, bimolecular or trimolecular).
Answer:
550 m/s
Explanation:
The average molecular speed (v) is the speed associated with a group of molecules on average. We can calculate it using the following expression.

where,
We can use the info of argon to calculate the temperature for both samples.

Now, we can use the same expression to find the average molecular speed in a sample of Ne gas.
