A chemistry student wants to study the adsorption of nitrogen gas on a copper surface at 298 K. The student knows that the Langmuir adsorption isotherm can be used to describe this system. They want to determine the maximum amount of nitrogen gas that can be adsorbed on the copper surface and the adsorption energy of nitrogen to the copper surface. Can you help the student to calculate these values using the Langmuir adsorption isotherm equation?
