Prоpаnоlоl is а drug thаt is classified as a beta blocker. It selectively binds beta receptors, which exist on the surface of certain cells, including the heart. Beta receptors in the heart are responsible for the fight or flight response by binding epinephrine and norepinephrine, which can speed up heart rate, raise blood pressure, and increase contraction force. Beta-blockers like propanolol compete with epinephrine in beta receptors to block this response, helping to control heart rate and blood pressure. S-propanolol in the presence of beta-receptors has a Keq of around 120000 at room temperature (25oC). What is the ΔG° of binding S-propanolol to the beta-receptor? (R = 8.314 J/mol*K)
