Problem: Consider the relationshipThe equilibrium constant for some hypothetical process was determined as a function of temperature (Kelvin) with the results plotted below.From the plot, determine the values of ΔH° and ΔS° for this process. What would be the major difference in the ln(K) versus 1/T plot for an endothermic process as compared to an exothermic process?

FREE Expert Solution

For the first part, we're being asked to determine the values of ΔH° and ΔS° for the process.

We're given the following relationship:

ln(K)=-H°RT+S°R


We can interpret the equation as:

ln(K)=-H°R(1T)+S°R    y  =      m     x  +   b


b = y-intercept → when x = 0
