The equilibrium constant for a reaction can be determined by using something called a van't Hoff plot, where data for Kc and T are related by the following equation: -AH AS In Ke R R In this equation, AH is the enthalpy of reaction, AS is something called the entropy of the reaction, R = 8.314 J mol-1 K-1, and T is the temperature in Kelvin. Answer the following questions regarding this reaction. A form of a dataset where Kc was measured as the Kelvin tempetature was changed has been plotted below. Give labels for the x and y axis to indicate what has been plotted on each, and indicate the units of each axis (if there are any). y = -4300.1 x + 16.885 R° = 0.9932 According to this plot, what is Kc at 308 K? You may omit units for your Kc value and report your answer to two significant figures. Your answer_ Determine AS, to three significant figures. Include units.
