What is p-n junction ?

-
Answer:-
A p-n junction is formed when we add a pentavalent impurity in a p-type semiconductor. l.e in a p-n junction one side is p-type semiconductor & another side is n-type semiconductor with forming a depletion region  in their junction.

A p-n junction is symbolically represented
as,
What is p-n junction ?
A p-n junction is generally called a Semiconductor diode.

What is Freundlich adsorption isotherm ?

-
Image
Explanation:- The variation in the amount of gas adsorbed by the adsorbent with pressure at constant temperature can be expressed by means of a curve termed as adsorption isotherm. According to freundlich isotherm,     The extent of adsorption of a gas per unit mass of adsorbent depends upon the pressure of that gas. I.e Look at the Graph,(x/m) vs (p) Equation (1) is the general form of freundlich adsorption isotherm. Case-1( at low pressure) If  x/m =kp¹ That implies 1/n=1 I.e  n=1 So at low pressure freundlich adsorption isotherm holds good because initially their is more adsorption occur. Case-2 (at high pressure) If x/m=constant  i.e1/n=0 That implies n=infinity So at high pressure x/m independent on pressure because after saturation pressure their is no adsorption occur due to no space on adsorbent. At saturation pressure Amount of gas adsorbed=amount of gas desorbed. Look at the logarithm graph of equation (1) This is all about freundlich adsor
