Calculate the root mean square (rms) average speed of the atoms in a sample of xenon gas at 0.15 atm and -55c
1 answer:
Answer:
Vrms is 149.7266 m/sec
Explanation:
The root means square velocity of a gas can be calculated as follows:
Vrms =
where:
R is the ideal gas constant = 8.3145
T is absolute temperature = -55 + 273 = 118 degrees kelvin
M is the molar mass of the gas = 131.293 grams = 0.131293 kg
Substituting with these givens in the above equation, we would find that the Vrms is 149.7266 m/sec
Hope this helps :)

write the overall rate law for the initial rate of the reaction as a fraction.
Rate=k(________/_________)
Answer:
The overall rate law for the initial reaction is =
Explanation :
Frist of all, all the common terms are cancelled out and written the overall reaction.
As we know that the rate depednant step is the slowest step of the reaction, rate law is :
rate =
But the problem is that SO3 cannot be written in the overall rate law because it is an intermediate.
Rate law for synthesis of S03 is as follows :
rate =
Hence when we substitute equation 2 in equation one,
Rate comes out to be =
