Options are:
1. Kelvin
2. Grams
3. Degrees Celcius
4. Degrees Fahrenheit

1. Kelvin

Explanation:

The standard temperature for scientific report is the kelvin.

According to the SI unit definition, temperatures should reported in Kelvin.

On the kelvin scale, the freezing point of water is 273kThe melting point of water is 373k The kelvin is widely accepted in scientific climes. It is possible to convert from this scale to another.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
