The answer would be: C. 160.3 J/mol*K
To solve this question, you need to know the equation for Gibbs free energy formula. Entropy is expressed as delta S. The temperature would be expressed as T. Don't forget that temperature use Kelvin as unit, not Celsius
The formula would be:
G= H- T*S
130.5 kJ/mol= 178.3kJ/mol - (25+273.15K)*S
(298.15K)*S=178.3kJ/mol - 130.5 kJ/mol
S= (47.8kJ/mol)/ 298.15K=
S= 0.1603 kJ/mol*K= 160.3 J/mol*K ------> 1kJ= 1000J

<u>Answer:</u> The given statement is true.
<u>Explanation:</u>
For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative.
The equation used to calculate Gibbs free energy follows:
Exothermic reactions are defined as the reactions in which energy is released in the form of heat. The enthalpy change 
of the reaction comes out to be negative for this kind of reaction.
Entropy change is defined as the change in the measure of randomness in the reaction. It is represented as 
. Randomness of gaseous particles is more than that of liquid which is further more than that of solids.
We are given:
A solid substance is converting into a gaseous substance.
As, the entropy is increasing. So, the entropy change is positive.
Thus, the above reaction is spontaneous.
Hence, the given statement is true.
As the name hypochlorous acid suggest that it is acidic, no matter what is the concentration of the acid, the acid solution is acidic as it provides hydronium or hydrogen ions to the aqueous solution.
HClO (aq) ↔ H⁺ (aq) + ClO⁻ (aq)
Hypochlorous acid or HClO is a weak acid, while NaOH is a strong base. The formation of NaOCl takes place when these two react. NaOCl is a salt of a strong base and a weak acid, and due to this, the solution of sodium hypochlorite is basic.
Sodium is the spectator ion, that is, it does not need to be represented at the time of demonstrating the net equation for the hydrolysis of sodium hypochlorite.
ClO⁻ (aq) + H2O (l) ↔ HOCl (aq) + OH⁻ (aq)
On observing the first equation, on the product side, there are hydrogen ions, which signifies that the solution is acidic, and if we observe at the second equation, on the product side hydroxide ion is witnessed that indicates that the solution is basic.
