Question

What is reaction isotherm? Describe briefly.

Answer 1

The graph between amount of gas adsorbed per unit mass of the adsorbent x /m and pressure of the gas at a constant temperature is known as AdsorptionIsotherm. ... The equation (iii) is called Freundlich adsorption isotherm.

Answer 2

The Gibbs free energy changes with the temperature and pressure of the thermodynamic system. The van 't Hoff isotherm can be used to determine the Gibbs free energy for non-standard state reactions at a constant temperature: ... When a reaction is at equilibrium, Qr = Keq.
