If temperature is above 0 degree Celsius, water doesn't naturally turn into ice. In fact, the opposite should be expected of.
The only way for water to turn into ice when temperature is above 0 degree Celsius is if there is an external source of energy, or in other words, not naturally occurring.
Therefore this reaction is non-spontaneous.
A non-spontaneous reaction has a delta G greater than 0, which is positive.
Therefore the sign of change in free energy in this case would be positive or A.
At temperatures above 0°C, what is the sign of the change in free energy for the conversion of liquid water to ice?
A. Positive
B. Zero
C. Negative
D. Not known
I don't this it is A. I thought it might be c.
