hey couple of qs, ways of thinking: 1) would the half-life change at all? 2) rate of formation oif P increases ie. now for every mole of R, 3 moles of P are being formed. But the rate at which R reduces, that would be the same, right? What do the rest of you think about this?

1) no, it wouldn't change, will still be 20days 2) -dR/dT = kR, will still be the same the only thing changing, the final moles of P, and rate of formation of P

i think the half life will change as the slope of concentration of P would be steeper

half life is determined by the reactant so even if the reaction wll be R->2P it will not change

accha i get it you mean to say rate constant as T1/2 = ln2/K

not really, but wait ill try explaining i was going with the deriavation, but i dont relly know how to explain itt without it Sir need help! :)

Go for it
iSoham
iSoham13mo ago
oh yea, from the product side, the rate constant changes i didn't want to use deriavation to keep it simple @ree ^

so t1/2 will be same?
iSoham
iSoham13mo ago
yes

let me verify

t1/2 is not 20 days

@!Nimay¡ any inputs on this? Office ja raha hoon and will prolly look at stuff properly only after 9th, isiliye aapko tag kar raha hoon 🙂 @Pistulya agar aapke koi inputs ho then most welcome too!

It's asking for the same graph the ans is B P -> 3P c 0 c-x 3x at t=20days -> c-x = 3x (concentration is same as per graph) x=c/4 using first order formula ln(Cnot/C)=kt ln(C not / 3Cnot/4) = k 20 k = ln(4/3) / 20 now t1/2 = ln2/k put k here t1/2 = 20 ln2 / ln(4/3) which is 48.() text solution khichadi, if any doubt in above, im here
