I got x=2 but its a big guess...............some flaws may be present.....

don't go on my convention

take initial mole as y and the decomposed as x=yα

x mole of reactant A decompose t ogive 1 mole of C and D

yes then it will be 2.. :)

But how i can know what is X... is it convention...

anyways... i solved one in chem again... [1]

small and capital x :P

According to my understanding of the question

x is the initial mole

X=αx is the decomposed mole of A

so here X=xα is asked not x

1 mole of D and 1 mole of C [7]

A ≈ mC+mD
moles at t=o x 0 0
at eq. x(1-α) mxα mxα

where mxα=1

let volume be V

A ≈ mC+mD

at eq. x(1-α) mxα mxα
V V V

as mxα=1
c(1-α) 1/V 1/V

1/V=cmα
as mxα=1 and x/V=c

so...

Keq=(cmα)m(cmα)m
c(1-α)

K=c2m-1(mα)2m = K
(1-α)

for α to be independent of c...... 2m-1=0... m=1/2

then α=2K/K+1
or x=(1+2K)
K

not x=2 :(

and reaction is A ≈ (1/2)C+(1/2)D
or 2A ≈ C + D

power cut... so may be later :(

Another answr x=1+2K/K

this time i'll post complete soln.. :)
in next post..

ufff........

Another try.... [3]

eureka123 ·

no.............x=2........surprised????????main bhi........par answer yahi hai.......bas solve nahin ho raha!!!!!!!

33
Abhishek Priyam ·

another guess x=K ?

[2]

ok let me do it again

24
eureka123 ·

nooooooooooooooo

24
eureka123 ·

yes 1mole of D and 1 mole of C

Abhishek Priyam ·

Is x=1/K [7]
