$$\Delta G = \Delta H- T \Delta S$$ Use this equation 
And the temperature should be in kelvin !

anonymous · Answer

I did use the equation and found -9.1...so does that mean that it should be C?

rushwr · Answer

yeah if u got that then of course yes ~

anonymous · Answer

Thank you so much! :)

rushwr · Answer

just want to reconfirm the value given for the entropy change !

anonymous · Answer

So it should always be Kelvin there, right?

rushwr · Answer

yep

Thank you! Now, I know for future reference :)
