Calculate the enthalpy change for the isomerization of butene to isobutene given that the enthalpy of combustion for butene is -2671.2 kJ/mol and the enthalpy of combustion for isobutene is -2678.6 kJ/mol. Assume that the molar enthalpy of formation of CO2 and H2O are -393.5 kJ/mol and -241.8 kJ/mol, respectively.

A chemistry student needs to determine the Langmuir constant and maximum adsorption capacity of a metal oxide nanoparticle using the Langmuir adsorption isotherm equation from experimental data obtained at different concentrations of a given adsorbate in the water. Determine the Langmuir equation parameters and plot the experimental data and the Langmuir model using a graph. Finally, interpret the results in terms of the adsorption behavior of metal oxide nanoparticle towards the selected adsorbate.
