In case of reaction with adsorbed intermediates, when some sites are energetically favorable compared to other sites, it is best described by
A) Langmuir isotherm
B) Temkin isotherm
C) Frumkin isotherm
D) none of the above

Question

Quizplus · Accepted Answer

The Temkin isotherm accounts for interactions between adsorbed molecules and assumes that the heat of adsorption of all the molecules in the layer decreases linearly with coverage due to adsorbate-adsorbate interactions. This makes it suitable for describing scenarios where some sites are energetically more favorable than others.
