1) 2P
2) Average speed does not change
Explanation:
1)
To solve the first part of the problem, we can use Boyle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:
where
p is the pressure of the gas
V is its volume
For the Xe gas in this problem we can write
where:
is the initial pressure
is the initial volume
is the final volume
Solving for p2, we find the final pressure:
So, the pressure has doubled.
2)
The average speed of the atoms/molecules in the gas is given by the formula
where
R is the gas constant
T is the absolute temperature (in Kelvin) of the gas
M is the molar mass of the gas
is known as rms speed of the particles in the gas
From the formula, we see that the speed of the atoms in the gas depends only on the temperature of the gas.
In the Xe(g) gas in this problem, the temperature is kept constant; therefore, since nothing changes in the formula, this means that the average speed also does not change.
Answer:
See explaination
Explanation:
The mole balance for a constant-volume batch reactor is given such as, For a first-order isothermal reaction, the time to reach a given conversion is the same for constant-pressure and constant-volume reactors. Also, the time is the same for a reaction of any order if there is no change in the number of moles.
