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: http://www.chem.ufl.edu/~itl/4411/lectures/lec_v.html

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.
