Question

Unit of Kc for the given gaseous reaction is 2 A+B= C + D is
1. M
2. M power -1
3. M power 3
4. M power -3
plz answer according to the given options...​

Answer 1

Answer:

The given reaction is :-

A+2B⇌2C+D

Initial moles : C 1.Sc 0 0

At eqm : (c−x) (I.Sc 2x x (let)

−2x)

Now, given that, At eqm, [A]=[D]

⇒c−x=x

⇒x=c/2

Now, At eqm,

[A]=C−C/2=C/2

[B]=
