Answer: -227 kJ
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
where,
n = number of moles
(as heat of formation of substances in their standard state is zero
Now put all the given values in this expression, we get
Therefore, the enthalpy change for is -227 kJ.
PH+pOH=14
pOH=9.32
pH=14-pOH=14-9.32=4.68
pH=4.68
pH=-log[H⁺]
-pH= log[H⁺]
![[H^{+}]= 10^{-pH} = 10^{-4.68}=2.09*10^{-5} [H^{+}] = 2.09*10^{-5}M](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%3D%2010%5E%7B-pH%7D%20%3D%2010%5E%7B-4.68%7D%3D2.09%2A10%5E%7B-5%7D%0A%0A%5BH%5E%7B%2B%7D%5D%20%3D%202.09%2A10%5E%7B-5%7DM)
