## What is the slope of Freundlich isotherm?

## What is the slope of Freundlich isotherm?

The values of slope and intercept in the graph of Freundlich adsorption isotherm at `25^(@)C` temperature are 0.5 and 0.4771 respectively.

## How do you calculate Freundlich isotherm?

Freundlich isotherm explains the behaviour of adsorption accurately. In the equation – x/m = k.P1/n (n > 1), ‘k’ and ‘n’ are constants that depend on the nature of the adsorbent and the gas at a particular temperature.

**How do you calculate Freundlich equation?**

The Freundlich equation in a linear mode yields a linear plot in which the slope is 1/n….7.1. 1.2. 1 Freundlich Adsorption Isotherm.

Equation | Isotherm | Equation# |
---|---|---|

q e = K r C e 1 + α r C e β | Redlich–Peterson nonlinear | 14 |

log ( K r C e q e − 1 ) = β l o g ( C s ) + ln ( α r ) | Redlich–Peterson linear | 15 |

### What is intercept in Freundlich isotherm?

In the Freundlich isotherm ((x)/(m)=k (p) ^(1//n)) plot of log “”x/m vs log p, the intercept is (where, x,m,p and k are mass of the gas, mass of adsorbent, pressure and constant which depend on the nature of the adsorbent, respectively)

### What is the value of intercept in Freundlich adsorption isotherm?

The value of slope and intercept in the graph of Freundlich adsorption isotherm at `25^(@)` C temperature are 0.5 and 0.4771 respectively.

**What is the value of n in Freundlich adsorption isotherm?**

Solution : In Freundlich adsorption isotherm, `(x)/(m)= kp^(1//n)` Where, x = amount of adsorbent m = amount of adsorbate The value of n is always greater than 1. So, the value of 1/n lies between 0 and 1 in all cases.

## What is Freundlich adsorption isotherm with mathematical expression?

C. xm=Kp−n.

## What is the value of intercept in the graph of in Freundlich adsorption isotherm?

The values of slope and intercept in the graph of Freundlich adsorption isotherm at 25oC temperature are 0. 5 and 0.

**How can the constant K and N of the Freundlich adsorption equation be calculated?**

1 Answer. k and n are constants which depend on the nature of the adsorbent and the gas at a particul temperature. Applying logarithm to the above equation logxm=logK+1nlogP log x m = log K + 1 n log P . → A graph is plotted taking log xm on y-axis and log P on x.

### What are the quantities which when plotted in Freundlich adsorption isotherm gives straight line?

Adsorption of a gas on a surface follows Freundlich adsorption isotherm. Plot of, logmx versus log p gives a straight line with slope equal to 0.5, then: (mx is the mass of the gas adsorbed per gram of adsorbent)

### What is Freundlich math form?

A. xm=Kp1/n. B.

**Which of the following equation represents Freundlich adsorption isotherm?**

The equation mx=kp1/n represents Freundlich adsorption isotherm. It is an empirical relationship between the amount of gas adsorbed by a given amount of solid adsorbent surface and pressure of the gas at a particular temperature.
