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
