Answer:
Temperature = 818 K
Explanation:
The given reaction is:
The change in enthalpy is: ΔH°= -109 kJ
The change in entropy is : ΔS° = -133.2 J/k = -0.1332 kJ/K
Based on the Gibbs-Helmholtz equation the standard free energy change is given as:
At equilibrium ΔG° = 0. therefore:
Answer: Option (d) is the correct answer.
Explanation:
It is known that length of a bond is inversely proportional to the bond strength. This also means that a single bond has long length due to which it is weak in nature.
And, a double bond is shorter in length and has more strength as compared to a single bond. Whereas a triple bond has the smallest length and it has high strength as compared to a double or single bond.
For example, carbon monoxide is CO where there is a triple bond between the carbon and oxygen atom.
Carbon dioxide is where there exists a double bond between the carbon and oxygen atom.
A carbonate ion is when two oxygen atoms are attached through single bond with the carbon atom and another oxygen atom is attached through a double bond to the carbon atom.
Hence, we can conclude that order of increasing bond strength of the given carbon oxygen bond is as follows.
Carbonate ion < carbon dioxide < carbon monoxide
