Answer: Δn for the following equation in relating Kc to Kp is 2.
Explanation:
The balanced chemical equation is:
Relation of with
is given by the formula:
Where,
= equilibrium constant in terms of partial pressure
= equilibrium constant in terms of concentration
R = Gas constant
T = temperature
= change in number of moles of gas particles =
Putting values in above equation, we get:
Thus the value of Δn for the following equation in relating Kc to Kp is 2.
C. the square root of the mass of the particles.
<h3>Further explanation </h3>Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or
the effusion rates of two gases = the square root of the inverse of their molar masses:
or
From this equation shows that the greater the mass of the gas, the smaller the effusion rate of the gas and vice versa, the smaller the mass of the gas, the greater the effusion velocity.
So if both gases are at the same temperature and pressure, the above formula can apply
