Answer:
The density of the ideal gas is directly proportional to its molar mass.
Explanation:
Density is a scalar quantity that is denoted by the symbol ρ (rho). It is defined as the ratio of the mass (m) of the given sample and the total volume (V) of the sample.
......equation (1)
According to the ideal gas law for ideal gas:
......equation (2)
Here, V is the volume of gas, P is the pressure of gas, T is the absolute temperature, R is Gas constant and n is the number of moles of gas
As we know,
The number of moles:
where m is the given mass of gas and M is the molar mass of the gas
So equation (2) can be written as:
⇒
⇒ ......equation (3)
Now from equation (1) and (3), we get
⇒ Density of an ideal gas:
⇒ <em>Density of an ideal gas: ρ ∝ molar mass of gas: M</em>
<u>Therefore, the density of the ideal gas is directly proportional to its molar mass. </u>
<u>Answer:</u> The value of for the reaction is 6.32 and concentrations of
is 0.094 M, 0.094 M and 0.106 M respectively.
<u>Explanation:</u>
Relation of with
is given by the formula:
where,
= equilibrium constant in terms of partial pressure = 3.45
= equilibrium constant in terms of concentration = ?
R = Gas constant =
T = temperature = 500 K
= change in number of moles of gas particles =
Putting values in above equation, we get:
The equation used to calculate concentration of a solution is:
Initial moles of = 1.00 mol
Volume of the flask = 5.00 L
So,
For the given chemical reaction:
Initial: 0.2 - -
At Eqllm: 0.2 - x x x
The expression of for above reaction follows:
Putting values in above equation, we get:
Negative value of 'x' is neglected because initial concentration cannot be more than the given concentration
Calculating the concentration of reactants and products:
Hence, the value of for the reaction is 6.32 and concentrations of
is 0.094 M, 0.094 M and 0.106 M respectively.
