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
<u>Answer:</u> The standard Gibbs free energy of the reaction is -15.8 kJ/mol
<u>Explanation:</u>
Relation between standard Gibbs free energy and equilibrium constant follows:
where,
= Standard Gibbs free energy = ?
R = Gas constant =
T = temperature = 298 K
= equilibrium constant = 581
Putting values in above equation, we get:
Conversion factor used: 1 kJ = 1000 J
Hence, the standard Gibbs free energy of the reaction is -15.8 kJ/mol
