Plz solve this
36. AH of water is 285.8 kJ moli, If enthalpy of neutralisation of monoacid strong base is -57.3 kJ mo-H, AH} of OH ion will be (a) -228.5 kJ mol-l (b) 228.5 kJ morl (c) 114.25 kJ mol-l (d) -114.25 kJ mol

samjh nhi aya sir
![eduncle-logo-app]()
how to calculate enthalpy of formation of H+
![eduncle-logo-app]()
okk sourav wait
![eduncle-logo-app]()
did you get it sir?
![eduncle-logo-app]()
sourav??
![eduncle-logo-app]()
yes sir
![eduncle-logo-app]()
and sourav is your doubt clear or still have doubt in this??
![eduncle-logo-app]()
still have the doubt
![eduncle-logo-app]()
sourav directly when you subtract these two you get enthalpy of formation of OH-
![eduncle-logo-app]()
As standard enthalpy of H2=0 O2=0 and arbitrarily we take H+ also as 0
![eduncle-logo-app]()
but what about heat of formation of H+
![eduncle-logo-app]()
We take arbitrarily it as 0
![eduncle-logo-app]()
cl- Na+ ke liye vhi 0 hoga?
![eduncle-logo-app]()
nhi mainly H+ ke liye krte hai
![eduncle-logo-app]()
ok sir.

option A
got it?
sir why enthalpy of formation of H+ is 0
check it
samjh nhi arha
okay later I'll explain you on the paper.
but heat of formation of H+ value 0 hai.. woh kaise mujhe nhi pata
check it
Heat of formation of H+(aq) is not zero. But it is arbitrarily assigned so by a convention, ΔH°(H+ aq) = 0. Hope this helps.
