In mcq no 3,what does delta G represents?

Maam In question no 3....delta G means?.... Is ka Delta H nai hona chahiya tha

[@Wickipedia--567]

All the spontaneous reactions are not exothermic(enthalpy change less than zero).
For example, ice changes into water absorbing energy from surroundings(endothermic) that is spontaneous.
Here, G is gibb's energy actually used to determine spontanity.i.e.negative value means spnyaneous and vice versa.

Plzzz ye question 3 explain kro

[@momnawaqas1410]

It means k ∆G agr negative ho ga 0 se km ho ga to reaction spontaneous ho ga or agr > 0 ho ga to reaction non spontaneous ho ga yahn pr endothermic confuse krny k liye include kia hai ❤️

[@asadsultan5976]

🔺️ G kia hy? Es ki samj nhi aye baki thek hy

Somebody explain mcq 20:((, what's s and v?

[@theshootingstar3154]

Ya glass calorimeter ma likha ha equation this tells the quantity of heat absorbed /evolved during reaction
q=heat
M =mass of reactants
S=specific heat of reaction mixture
T=change in temperature

Can u explain plz

Nhi hm exactly to Nhi kah sakta na k ∆V=0 obliviously ham heat provide kar rha ha to system me kuch changes aaegi volume me

[@MuhammadAbdullah-sj2qb]

Thanks alot mam amazing

[@hafsakhan7655]

I think 25 mai D option correct hai

[@Wickipedia--567]

@@hassaanmalik1122 when solid changes to liquid, intermolecular forces become weak so there is increase in volume & when liquid changes to solid the molecules come closer to each other and volume decreases!!
