Binary number system.

-
The binary number system consists of only two digits. These 2 digits are 0 & 1. The binary number system is known as base 2 system because it has 2 digits. The binary system is a place value system in which each binary digit has its own value expressed as a power or 2. The place to the left of binary point are positive powers of 2 and places to the right are negative power of 2. The term binary digit is known as bit. The left most binary digit is called the most significant bit(MSB) and the right most binary digit is called the least significant bit (LSB).

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
