For a certain reaction, the changes in enthalpy and entropy are ∆Hrxn =  {dH} kJ/mol                        ∆Srxn =  200. J/mol∙K Calculate the temperature at which this reaction crosses over between spontaneous and nonspontaneous.  Hint: pay attention to units. Answer format:  Enter a number in standard (not scientific) notation in Kelvins, but do not enter the units.  Enter 3 sig figs.
