What is Freundlich adsorption isotherm and Langmuir isotherm?
At a given temperature, the extent of adsorption will increase with the increase of pressure of the gas. The extent of adsorption is measured as x/m, where mi= is the mass of adsorbent and x that of adsorbate. At low pressure, x/m varies linearly with p. As per Freundlich adsorption equation Taking log both sides of the equation, we get, At low pressure, x/m=kP At high pressure, x/m=kPo This is called Freundlich adsorption isotherm at a constant temperature. Freundlich isotherm fails at high pressure and is only for physical adsorption. Langmuir isotherm is represented as x/m=ap/(1+bp) (a and b are constants) At very high pressure,(bp>>1) x/m=a/b At very low pressure,(bp<<1) x/m=ap
Is there a simple equation to calculate the concentration given the absorbance and a time?
You need a graphic concentration versus absorbance.
Are there any synonyms for the words chemical equation?
A chemical equation written in symbols is sometimes called a balance equation, because the numbers of each kind of atom have to balance on both sides. If it's written in words it's called a word equation.
What is H ion concentration of ph11?
The following equation will get you to the answer where [H+] is the concentration of hydrogen ion: pH = -log( [H+] ) or [H+] = 10-pH
What is the formula of ilkovic equation in the diffusion current?
ilkovic equation gives us the chance to know what is the potential difference of any system.the potential difference can easily be calculated with the help of Hg-drop!there is an equation with the help of which we can know very other things except the potential difference!
What is hill isotherm?
The Langmuir equation (also known as the Langmuir isotherm, Langmuir adsorption equation or Hill-Langmuir equation) relates the coverage or adsorption of molecules on a solid surface to gas pressure or concentration of a medium above the solid surface at a fixed temperature.
What are the disadvantages of Frenlich adsorption isotherm?
Frenlich adsorption isotherm has no theoretical basis. There are high chances of it failing when the concentration of the adsorbate is high. The equation is, usually, invalid at high pressure.
What are the advantages of solving a graphical equation algebraically?
You get the exact solution.
What is the difference between algebraic solution and graphical solution to an equation?
whats the difference between solving an inequality by algebriac vs graphical
What is the characteristic of chemical equation?
A chemical reaction is a graphical representation of a chemical reaction.
Why do you do y equals mx plus b to determine the slope intercept form?
because that is the mathematical equation of the graphical representation. If x=0 the the value of the function i.e. y = b. This implies y intercept
How do you determine if an equation in x and y define y as a function of x?
The graphical way is probably the simplest. Draw a graph of the equation. Hold a ruler parallel to the y axis and slide it from left to right. If, at any point, the ruler touches the graph at more than one point then you do not have a function.
What does a reactant do in an equation?
The reactants in the equation determine what product you get.
Determine the nature of the solution of the equation?
The answer will depend on the equation.

How do you find the zeros?
Solve the equation - by whatever means available to you: factorising, graphical, numerical approximations, etc.
What is the equation you use to determine for momentum?
The equation is force multiplied by accelaratin
