Question

10.One -fourth of a reaction is completed in 32 minutes What is the half life period of this reaction ?​

Answer 1

Answer:

hey mate .your answer is 32 minutes is the one fourth and the half period of life period is 32x2 is equal to 64p

Answer 2

Answer:

One - fourth means - - >

1/4 ×100

i.e. 25%

Hence 25% completes in 32 minutes

So for completing half life i.e. 50%

25 %more needed

NOW......

Then 25 % takes 32 minutes

And hence 50% needs (32 +32) minutes

I.e 64 minutes

(u must provide reaction equation so that I gotta know whether it is zero order reaction or first order reaction)

For zero order use this->

: t 1/2 = [R] 0 /2k

For a first-order reaction,

the half-life is given by: t 1/2 = 0.693/k
