Answer:
-30.7 kj/mol 
Explanation:
The standard free energy for the given reaction that is the hydrolysis of ATP is calculated using the formula:  ∆Go ’= -RTln K’eq
where,  
R = -8.315 J / mo
T = 298 K
For reaction, 
1. K′eq1=270, 
∆Go ’= -RTln K’eq
= - 8.315 x 298 x ln 270
=  - 8.315 x 298 x 5.59
= - 13,851.293 J / mo
= - 13.85 kj/mol
2. K′eq2=890
∆Go ’= -RTln K’eq
= - 8.315 x 298 x ln 890
=  - 8.315 x 298 x 6.79
=  - 16.82 kj/mol
therefore, total standard free energy
= - 13.85 + (-16.82)
=  -30.7 kj/mol
Thus, -30.7 kj/mol is the correct answer.
 
        
             
        
        
        
The chemical compound's empirical formula is NS.
The chemical compound's molecular formula is N4S4.
<h3>What does a chemical empirical formula look like?</h3>
- The empirical formula of a compound that gives the proportion (ratios) of the elements in the complex but not the precise number or arrangement of atoms is known as an empirical formula. 
- This would be the compound's element to whole number ratio with the lowest value.
<h3>What sort of empirical formula would that be?</h3>
- The chemical structure of glucose is C6H12O6. Every mole of carbon and oxygen is accompanied by two moles of hydrogen. 
- Glucose has the empirical formula CH2O. 
- Ribose has the chemical formula C5H10O5, which can be simplified to the empirical formula CH2O.
