Temperature dependence of equilibrium constant

Hard problem

Was a data table provided with this problem?  Don't see how you could calculate Keq without knowing concentrations at different temperatures.


To understand the equation check out this site:


The equation above is in the form of a straight line;   y =  m x  + b

where y = ln K

             m  =  -DeltaH/R

              x  =  (1/T )   where T is in Kelvin

              b =  Delta S / R

Using the Keq values calculated above (from the missing data), and their corresponding T values (converted to Kelvin), find the values for ln K  and 1/T and plot them.

Hope this helps.
