Plz solve this

option a,b, and c are correct

Did you check this Sourav??

samjh nahi aya

value to given hai....

https://doubtnut.com/question-answer-chemistry/from-the-following-data-mark-the-options-where-deltah-is-correctly-written-for-the-given-reaction-gi-19379158 check this

now got it or any doubt??

not opening

im not able to comment also

app problem may be....check it later and if any doubt comes then please ask

video hi nahi arha

okk wait

https://youtu.be/dMr3lvTFba8 check

sir lekin samjh mai nahi arha kuch vhi video se 🙁

which part you have problem ..??

change in enthalpy nikal lo hr case me value given hi hai

option a mai kya kara samjh mai nahi arha

HA and BOH ka value diya hai ionisation ka...last line me...or H20 ka diya hai first me...neutralisation reaction..

maine aise kara tha.. but enthalpy of formation of BA, BOH, HA kaise solve krna hai nahi aya muhe

sourav for 1st equation only two value is given to you...first is formation of H20 and second is ionisation of HA...

wait let me confrm is there any concept missing

ok

sourav forward reaction to neutralisation reaction hai...to uska value formation of water se diya hua hai...or fr reactant side ionisation if HA ka value diya hua hai or BOH given hai strong base to uska enthalpy almost constant hoga...so Value aa jayenge -57.3+15=-42.3...and next 3 options samajh gye??

enthalpy of formation of H2O is enthalpy of neutralisation?

what about enthalpy of formation of BA in product side?

sourav clearly it is not mentioned here..just given boh is strong base and ha ionises...but when both are strong then the heat of neutralisation is nothing but it is heat of formation of water

so by considering this you can proceed...as here forward reaction show neutralisation

one more qs why are we adding the enthalpy it should be product - reactant na?

sourav it is not added...it is -57.3-(-15).. as HA ionises...the enthalpy is given as -15 ...see the third equation of this type there HA gaseous ionises

but in qs it us given enthalpy of ionization is +15..why take negative?

in first option enthalpy of formation of BA and BOH are taken as 0..why?
