show sketches of the graphs and answer both questions please.

A colleague claims that a sample of Au nanoparticles are being prevented from undergoing Ostwald ripening because of the presence of thiol stabilisers. Suggest, with a justification, an analytical technique that you could use to confirm the presence of thiol on the Au nanoparticle surface and sketch the graph you would expect to see. ( 9 marks) The nanomaterial MoS2 has shown promise in the remediation of radioactive waste, as it is able to adsorb metallic radionuclides such as Cs+from aqueous solution. Using the data plotted in Figure Q5, calculate the enthalpy of adsorption of the radionuclide onto the MoS2 surface and determine whether the adsorption is occurring via physical or chemical interactions.
