All of that is correct i am confused on what u are asking us to answer
Explanation:
Answer : The value of is -24.9 kJ/mol
Explanation :
First we have to calculate the value of 'Q'.
The given balanced chemical reaction is,
The expression for reaction quotient will be :
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
Now put all the given values in this expression, we get
Now we have to calculate the value of .
The formula used for is:
............(1)
where,
= Gibbs free energy for the reaction = ?
= standard Gibbs free energy = -28.0 kJ/mol
R = gas constant =
T = temperature = 298 K
Q = reaction quotient = 3.375
Now put all the given values in the above formula 1, we get:
Therefore, the value of is -24.9 kJ/mol
Answer:
<h3>When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. ... When they break down, they release chlorine or bromine atoms, which then deplete ozone.</h3>

To solve this half-reaction method, we divide the reaction into two equations- reduction and oxidation side. The oxidation is simply Ag= Ag+ + e-. The reduction side is 4H+ + NO3-+e-=NO+2H20. H2O is used to balance O and H+ is used to balance H. Hence the final equation is Ag+4H+ + NO3-= NO+2H2O.
