Answer:
Ratio is 4:1
Explanation:
from graham's law of gaseous diffusion:

but Ra = 2Rb:

Answer is Chemical change
Answer:
The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons's law). ... The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).
Answer:
temperature and mechanism
Explanation:
Arrhenius equation gives us the idea about the factors affecting equilibrium constant.It is given as:
<h3>

</h3>
where k=equilibrium constant
A=pre-exponential factor
=Activation energy
T=temperature
R=Universal gas constant
<h3>It is clear that k depends only on temperature and activation energy.</h3>
Activation energy of a reaction is different for different mechanisms or pathways.Hence k depends on both temperature and mechanism.
