Your question looks a bit incomplete as you have the same contents in options a) and d). According to your list, I can't see the correct answer, but I can give you one.The difference between the potential energy of the products of the potential energy of the reactants is equal to the enthalpy of the reaction.

Answer:
The answer is "
"
Explanation:
When 
 is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:
  In this, the 
 is a weak acid so, it not completely dissociated.
 were strong electrolytes they are completely dissociated.
The 
 is a strong acid so, it is completely dissociated So, the net ionic equation is:

 
        
             
        
        
        
I think the answer might be 51.14% since the formula had to equal a 100% just add 41.86 and 6.98 and subtract the sum to 100.
