* 2B(g) the
following concentrations where measured
at 25°C. The Kc for this temperature is 1
Is the reaction at equilibrium?
[A] = 4 M
[B] =2 M

For the reaction Ag 2Bg the following concentrations where measured at 25C The Kc for this temperature is 1 Is the reaction at equilibrium A 4 M B 2 M class=

Respuesta :

Answer:

Yes

Explanation:

By definition, the equilibrium constanct, Kc, for the reaction A ⇒ 2B is

= [A]^1 / [B]^2

Substitute [A] = 4 and [B] = 2 in the equation,

[A]^1 / [B]^2

= 4^1 / 2^2

= 1

= Kc

So yes the reaction is at equilibrium.

Let's find K_c

[tex]\\ \rm\Rrightarrow K_c=\dfrac{[B^]^2}{[A]^1}[/tex]

[tex]\\ \rm\Rrightarrow 1=\dfrac{2^2}{4}[/tex]

[tex]\\ \rm\Rrightarrow 1=\dfrac{4}{4}[/tex]

[tex]\\ \rm\Rrightarrow 1=1[/tex]

Yes it's at equilibrium
