A particular reaction has AHⓇ = 55 kJ and AS° = 101 J/K, at 25°C. A) Calculate the temperature (in K) at which AG° = 0. B) What is the significance of (what does it mean when or what does it indicate when) AGº = O?
A particular reaction has AGⓇ = 50.0 kJ and A5° = 120.0 J/K. Calculate AHⓇ for this reaction at 25°C.
For a particular reaction, AH = -14.20 kJ/mol and AS = -198.5 J/(mol.K). Calculate AG for this reaction at 298 K. AG = 73.35 kJ/mol
6) Some unimolecular reaction, A → B, has a AH = -31.2 kJ/mol and a AS = 4.8 J/mol K. At 25 °C the reaction has a rate constant of 0.155 5-1. Raising the temperature to 37 °C increases the rate constant to 0.216 s-. Draw the potential energy surface (in terms of AG vs reaction coordinate) for this reaction at 25 °C (assume Hand S do not change with temperature).
