For a Reaction to be exothermic hydration energy should be higher than the lattice energy. If compounds do not dissociate into ions then reaction will never be exothermic. Saluting your teaching Sir

Sir sulphuric acid wala concept jankar bahut अच्छा लगा

[@ranvijaypratapsingh8717]

Superb..... And you are so polite

[@SharifulIslam-pb1zf]

CaCO3 in water is an exothermic process.So, enthalpy change must be negative. By the way, thanks for your nice presentation

[@learningskillsbyrohitraut4533]

No, sorry to say but CaCo3 in water is not exothermic as CaCo3 is quite stable, it's lattice energy is very high so i doesn't break into its constituents ions.

[@TanvirAhmed-bk9fl]

[@babunavalyal6849]

Sir why formation of calcium carbonate is not an enthalpy of formation??can you please answer this....please make video on this

[@learningskillsbyrohitraut4533]

Enthalpy of formation of CaCo3 is the energy released when one mole of CaCo3 is formed from most stable form of of Carbon, calcium and oxygen but actually CaCo3 is formed from Cao and Co2 so in this case energy released will be different.

[@veenasharma6647]

Please add lecture on statement and concept of residual entropy

I knw but cnt help people are more intrested in nonsence content and more over they want viideos which can help them top exams in 10 days 😪😪😪😪😪😪😪😪😪😪😪

[@mdshamshsdkhan2245]

Absolutely correct

[@bhupinderkamboj2647]

Sir i have doubt ... U said that enthalpy means heat change at constant temperature and pressure.... But here temperature is changing... And one thing more in thermodynamics we use sign convention as energy released negative and energy absorb positive but here u use reverse.... Please reply sir....

[@rajeswarinunna105]

I think For ex:- in case of ∆latticeH As energy is given by the solvent to solute to break it's lattice structure that means energy is lost from the solvent so -ve (with respect to solvent) but at the same time energy is absorbed by the solute so +ve(with respect to solute)

[@rajeswarinunna105]

If I'm wrong pls forgive me

[@chemistryuntold]

you r right.

[@rajeswarinunna105]

Sir said that enthalpy means heat at constant Pressure only. (not temperature)

[@hcsjaat]

@@rajeswarinunna105 yes you are right

[@Cmagoyat]

Sir if ∆H solution ki value positive aati h ....iska matlb solution hot hoga ????or if iski final value negative aati h to cold ???

[@chemistrymaderousing-bytus2100]

POSITIVE COLD NEGATIVE HOT.. as exo (delta H < 0) releases heat making container (thermodynamic surrounding) hot.. and endo (delta H >0)cold as it absorbs heat from surrounding..

Thnk u sir

[@heartsking7456]

Mzaa a gya sir

[@AnkitMathuram]

Sir, adding water to acid is exothermic reaction and since only enthalpy of Hydration is present, the enthalpy of solution is +ve. But we know, that for exothermic reaction the enthalpy of the reaction is -ve as heat is released by the system. Where does the contradiction lie then? Please Answer Sir.

[@chemistryuntold]

Point of view and reference.

[@learningskillsbyrohitraut4533]

+ve sign indicates energy is absorbed and -ve sign shows energy is released. To break crystal energy has to supply so lattice energy is +ve and once dissociated into ions due to ion dipole interaction energy is released so hydration energy is -ve . sum of this two energy is called called solution enthalpy if this comes out to be +ve, it is endothermic otherwise exothermic.

[@learningskillsbyrohitraut4533]

it depends on point of view,you may adpot any sign convention. But meaning will be the same

[@praveengawali9826]

Concepts got cleared.....

[@tecindia9519]

sir nacl is also a electrolite but it cool the water..........why sr plz explain

[@pushkarnegi4274]

Lattice energy of NaCl is more than hydration energy.

[@chandrakantyadav37]

Nice one sir...plz keep it up

[@chemistryuntold]

Thankyou

[@vishalbhadoriya3416]

Its very helpful

[@landesaiprasad4305]

Small correction when urea is dissolving we call enthalpy of solution not enthalpy of lattice energy Urea is not at all a ionic compound then how we call it lattice ?

Sir aap konsa book follow kar rahe hen chistry ka.....??

[@mandeepmahara7210]

Well explained sir but let me tell u my query When Sulphuric acid is added to water doesn't we say There will be more enrgy comes out Bcz of Enthalpy of neutralisation which is somewhere more than Enthalpy change of Hydration? Actually i am confused with Neutralisation and Hydration Hope u will surely help me asap

[@pushkarnegi4274]

Sir when suphuric acid added to water heat is evolved due to hydration only. When sulphuric acid added to a base then heat is evolve due to neutralisation. Which enthalpy is more it depends on various factors i

But alakh sir ne ye wala topic nahi padaya tha tho mai kise aur channel se dekhne wala tha aur really this vedio was best for me. Thanks
