Homework Help: Chemistry 152

Posted by Car on Saturday, July 3, 2010 at 11:09am.

For a certain reaction, the enthalpy change is -148.5 kJ, the entropy change is 256 J/K, and the free energy change is -250.1 kJ. At what temperature is the reaction occurring, in C?
Choose one answer.

a. 85
b. 102
c. 124
d. 158
e. 210

I keep using equation delta G=delta H-T(delta S).......I plug in numbers but keep getting 147.5K then if I am trying to get celcius I get 125 which only thing close is 124 and not sure if its right once I manipulate to get T.
