Answer:
I pretty sure it's the pH level 7
<u>Answer:</u> The change in enthalpy for the given system is -642.8 kJ/mol
<u>Explanation:</u>
To calculate the change in enthalpy for given Gibbs free energy, we use the equation:

where,
= Gibbs free energy = -717.5 kJ/mol = -717500 J/mol (Conversion factor: 1 kJ = 1000 J)
= change in enthalpy = ?
T = temperature = 337 K
= change in entropy = 221.7 J/mol.K
Putting values in above equation, we get:

Hence, the change in enthalpy for the given system is -642.8 kJ/mol

Explanation:
When an element is displaced by another element in a compound then it is known as a single displacement reaction.
For example,
is a single displacement reaction.
Similarly when a hockey player has the puck in the corner of the rink. An opposing player muscles him aside and emerge with the puck displays that a single player is displacing a person.
Thus, we can conclude that this situation is most analogous to single displacement reaction.
