Answer:
The reaction H2O(g)+C(s) -> CO(g)+ H2(g) is NOT spontaneous because its ΔG = 91 kJ/moles
Explanation:
ΔG is calculated by ΔH - TΔS
ΔG = ΔH - TΔS
ΔG = 131.3 kJ/mole - 298K . 0,134kJ/mole K
ΔG = 91.068 kJ/moles
Be careful with the ΔS, because you have J, and in ΔH, you have kJ
Answer:
The answer to your question is False.
Explanation:
Data
1 mole of NH₄NO₃
0.75 moles of N₂O
Percent yield = 25%
Chemical reaction
NH₄NO₃ ⇒ N₂O + 2H₂O
Process
1.- Determine the theoretical yield
1 mol NH₄NO₃ ------------- 1 mol of N₂O
2.- Calculate the percent yield
Percent yield = Actual yield / Theoretical yield x 100
-Substitution
Percent yield = 0.75 / 1 x 100
-Simplification
Percent yield = 0.75 x 100
-Result
Percent yield = 75%
Conclusion
False, the actual percent yield is 75%
