Answer:
The reaction is spontaneous when T> 0.98 Kelvin OR T> -272.17°C
Explanation:
Step 1: Data given
ΔH = 131.3 kJ/mol = 131300 J/mol
ΔS = 133.6 J/K*mol
T = 298K
Step 2: The balanced equation
C (s) + H2O (g) --> CO (g) + H2 (g)
Step 3: ΔG
For a reaction to be spontaneous, ΔG should be <0
When ΔG > 0 the reaction is spontaneous in the reverse direction.
ΔG = ΔH - TΔS
Since ΔG<0
ΔH - TΔS <0
Step 4: Calculate T where the reaction is spontaneous
ΔH - TΔS <0
131300 J/mol - T*133.6 J/K*mol <0
- T*133.6 J/K*mol < -131300 J/mol
-T <-131300 /133.6
-T< -982.8 Kelvin
T> 982.8 Kelvin OR T> 709.6°C
The reaction is spontaneous when T> 982.8 Kelvin OR T> 709.6°C
At 298 K this reaction C (s) + H2O (g) --> CO (g) + H2 (g) is <u>not spontaneous</u>
POF₃
<h3>
Further explanation</h3>
A certain compound is made up of one phosphorus (P) atom, three fluorine (F) atoms, and one oxygen (O) atom.
<u>Question:</u>
What is the chemical formula of this compound?
<u>The process:</u>
The chemical formula of a compound states the type and the relative number of atoms contained in the substance.
- Element symbols are written with capital letters, in this case, P, O, and F.
- But if in other cases, these elements, for example, sodium or iron, the first letter is capital while the second letter is lowercase. Here is the writing:

- We can add the number of atoms present as a subscript and it applies to three fluorines.
As follows, the chemical formula of this compound is 
The names of these compounds are as follows:
- Phosphoric trifluoride
- Phosphoryl fluoride
- Phosphorus oxyfluoride
<u>Notes:</u>
- POF₃ is a colorless and similar gas to POCl₃ or POBr₃. Remember that F, Cl, Br are included in the halogen group.
- The molecular shape of POF₃ is tetrahedral with a bond angle of 103°.
