Fowler-Guggenheim Isotherm Non-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

fowlerguggenheimanalysis(Ce, theta, Temp)

Arguments

Ce	is equal to Co which is the numeric value for the initial concentration
theta	is the fractional surface coverage
Temp	temperature

Value

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