A chemistry student needs to calculate the enthalpy of adsorption for NH3 gas onto a silica gel adsorbent. The mass of silica gel used is 5.00g and the initial temperature of the system is 298K. The student also measures the equilibrium pressure of the NH3 gas at 298K to be 0.222atm. To carry out the experiment, the student passes NH3 gas over the silica gel and waits until it reaches equilibrium. The temperature of the system is then measured to be 305K. Using this information, what is the enthalpy of adsorption of NH3 onto the silica gel adsorbent in kJ/mol?
