The answer is -112.4 kJ/mol
Explanation
This is graph is called Van't Hoff plot
lnKeq = - ∆H°/RT + ∆S°/R
Slope = - ∆H°/R
∆H° = - slope × R
= - (1.352 ×10^4 K × 8.314 ( J/K mol )
= - 1.124 × 10^5 J/ mol
= - 112.4 kJ / mol

A chemical reaction was conducted at several different temperatures (measured in K) and the equilibrium constant was measured at each one. Plotting the data on a graph with ln K on the y-axis and 1/T on the x-axis gives a linear plot with slope = -4594.6 and y-intercept = 13.6. What is ΔrH° (in kJ mol-1) and ΔrS° (in J mol-1 K-1)?

A chemical reaction was conducted at varying temperatures so that the equilibrium constant, K was determined at each. Thereafter it was assumed that the reaction enthalpy, DeltarxnH° was independent of temperature and a graph of 1/T (in Kelvin) vs. ln K was plotted yielding a straight line with a slope of –1586.33. What was the resulting DeltarxnH° value and was it an exothermic reaction
