Which of the following assumption was not considered during the derivation of Langmuir adsorption isotherm?

In an experiment to determine the quantum yield of a photochemical reaction, the absorbing substance was exposed to 500 nm light from a 100 W source for 3000 s, with 80% of the incident light being absorbed. If 0.40 mol of the absorbing substance was decomposed, then the primary quantum yield is
