Answer:
The measurable quantities of the gases at equilibrium must be constant
Explanation:
Measurable quantities for the gases at equilibrium includes rate of formation of , rate of formation of
, pressure of
and pressure of
.
At equilibrium, rate of forward reaction is equal to rate of reverse reaction.
Rate of forward reaction infers rate of formation of and rate of backward reaction infers rate of formation of
.
As rate of formations from both direction are equal therefore pressure of both gaseous species remains constant.
Answer : The volume of gas will be, 113.5 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 60 atm
= final pressure of gas = 30 atm
= initial volume of gas = 29 L
= final volume of gas = ?
= initial temperature of gas = 115 K
= final temperature of gas = 225 K
Now put all the given values in the above equation, we get:
Therefore, the volume of gas will be, 113.5 L
The density : 1.96 g/L
<h3>Further explanation</h3>Ideal gas Law
Pv=nRT
where
P = pressure, atm , N/m²
V = volume, liter
n = number of moles
R = gas constant = 0.082 l.atm / mol K (P= atm, v= liter),or 8,314 J/mol K (P=Pa or N/m², v= m³)
T = temperature, Kelvin
so for density,
MW CO₂ = 44 g/mol
