Cis-platin is a treatment for certain types of cancer, but the trans-isomer is not effective. Use the data below to answer the following:

Cis-platin delta H= -467.4(kJ/mole at 298K) delta G= -228.7(kJ/mole at 298K)

Trans-platin delta H= -480.3 (kJ/mole at 298K) delta G= -222.8(kJ/mole at 298K)
a) Which isomers is favored?
I know that this one is the Cis-isomer

b) What is the equilibrium constant, K for the conversion of trans- to cis- isomer?

c) Is the RXN endo or exo thermic?
I know it is endothermic

d) At what temperature does the production of cis-platin become spontaneous?

All help is greatly appreciated!!
