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?

Question

Choose one answer. a. 85
b. 102
c. 124
d. 158
e. 210

Answer 1

delta G = delta H -T*delta S.
You have all of the numbers. Just plug them in and solve for T. Remember to convert T(in Kelvin) to C since the answer is to be in C.
