Fowler-Guggenheim Isotherm Linear Analysis

Description

In Fowler-Guggenheim isotherm model, the lateral interaction of the adsorbed molecules is taken into consideration. This is formulated on the basis that the heat adsorption process may vary positively or negatively with loading.

Usage

fowlerguggenheim.LM(Ce, theta, Temp)

Arguments

Ce

is equal to the numerical value for the equilibrium capacity

theta

is the fractional surface coverage

Temp

temperature

Value

the linear regression, parameters for Fowler-Guggenheim isotherm, and model error analysis
