Hi!
The perpendicular distance 2.4cm, is much less than the distance to both endpoints of the wire, which is aprox 1m. Then the edge effect is negligible at this field point, and we can aproximate the wire as infinitely long.
The electric filed of an infinitely long wire is easy to calculate. Let's call z the axis along the wire. Because of its simmetry (translational and rotational), the electric field E must point in the radial direction, and it cannot depende on coordinate z. To calculate the field Gauss law is used, as seen in the image, with a cylindrical gaussian surface. The result is:
Then the electric field at the point of interest is estimated as:
Answer:
Explanation:
We are given:
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:
The chemical reaction follows the equation:
The expression for for the given reaction follows:
We are given:
Putting values in above equation, we get:
Hence, the partial pressure of the at equilibrium is 0.017 atm.
