For the reaction at 25 degrees C, 2NO2(g)<----> N2O4(g), the values of delta H and delta S are -58.03 Kj/mol and -176.6 J/K mo, respectively. What is the value of delta G at 45 degrees C? Assume that delta H and delta S do not depend on temperature. At what temperature is delta G=0? Is delta G negative above or below this temperature.
