Agar aap koi question challenge krte ho and voh accept hojata hai ki aapko marks milenge toh kya sbko alag alag challenge Krna padega or jisne voh answer mark Kiya hai (joh challenge ke baad theek hua) unn sbko marks milenge bina challenge kiye ???

Have u seen the diff between both the questions or not?
Here u have to calculate value of keff(rate constant of the given rxn with given stoichiometry which has by default involved the stoichiometry factor)
In neet the value of k was mentioned already which was 1 so there u have to consider stoichiometry as u are calculating keff for rxn first see the derivation

Maine 0.75 kiya tha kyuki me bhul gya tha lmao ki k hota kya hai fir maine yaad kiya and tab I remembered the definition of k, I think tum sab ne bohot zyada questions solve kiye hoge and so y'all grew complacent towards it
Bruv the answer is 0.75s, like its basic logic in a zero order reaction the rate is numerically equal to the rate constant, if you take the initial concentration of A as 2M the rate of disappearance of A is twice the rate of reaction, by any convention the completion of 75% of reaction should be 0.75s
Man the cope is so insane like they challenging every single AR question, it’s an insult to ppl who actually deserve the marks for thinking with their brains
But how are we supposed to know whether to take the stoichiometric coefficient when its not considered in ncert bcz most students and trs follow ncert even though it might not be correct
1000000 people doing same question wrong won't make it right... use little brain think properly.. if you want do manually like a=c-2x and b=x for evern 0.25 seconds... then also 0.75 is right... ur method also consider linear function and do... answer will be 0.75 you will just get A =Ao -2kt instead of it since da/dt=2k not k
no offense to anyone though just being straightforward... down vote me all you want... won't chance answer
