Question

What is the use of this equation?​

Answer 1

Explanation:

we use this equation in kc calculation

in this we find the concentration and partial pressure of the comopound which is in equilibrium so u will get to know about in chemical equilibrium. if wnt the proof of the formula then. I will give it to u

let the reaction is A^a+B^b=C^c+B^b

we know that

rate of forward reaction is equal to rate of back ward reaction

where Rf(rate of forward reaction)

Rb(rate of backward reaction)

Rf directly proportional to [A]^a[B]^b

[ ] = concentration term or active mass

Rb directly proportional to [C]^c[D]^d

Rf=Kf[A]^a[B]^b (Kf=rate constant for forward reaction)

Rb=Kb[C]^c[D]^d (Kb=rate constant for backward reaction)

Rf=Rb

Kf[A]^a[B]^b=Kb[C]^c[D]^d

Kf/Kb=[C]^c[D]^d/[A]^a[B]^b Kf/Kb=Kc

Kf/Kb =Kc is new rate constant which is know as concentration term

Kc=[C]^c[D]^d/[A]^a[B]^b

is known as new kc calculation for equilibrium constant
