Solution:
{\bf Single choice}\\
The following figures were reported for the reaction $A + B \to C$\\Which description is $\uline{\mbox{\bf not appropriate}}$?
\begin{parts}
\part Species $A$ could be adsorbed on the surface but only very weakly adsorbed.
\part Species $A$ is not adsorbed on the surface.
\part Species $B$ is adsorbed on the surface.
\part Species $A$ is strongly adsorbed on the surface.
\part Species $C$ is adsorbed on the surface.
\end{parts}
