Problem- You are studying a new reaction and measure the DHo as -7.7 kJ/mol and DSo as 44.1 J/mol/K. What is the DGo for this reaction? Report your anser in kJ/mol to the nearest 0.1 kJ/mol. Assume the reaction is occuring at body temperature, 37oC.
If possible just a brief explanation how you got the answer?
