Fig. 5. (a) Temporal evolution of limonene pressures in the reaction cell and (b) adsorbed limonene concentrations on SiO2 as a function of time for three different limonene equilibrium pressures, 7 (light grey), 14 (dark grey) and 22 (black) mTorr. Error bars represent the standard deviation between triplicate replicates of the same experiment.
