What is the equilibrium concentration of C at 30C for the gaseous reaction A B ltgt 2C if Kc 40 and Ali Bi 20 M M class=

Respuesta :

Answer:

56

Explanation:

[tex]\\ \rm\Rrightarrow K_c=\dfrac{[Products]}{[Reactants]}[/tex]

Now

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

Put values

  • [C] be x

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

[tex]\\ \rm\Rrightarrow x^2=4(4)[/tex]

[tex]\\ \rm\Rrightarrow x^2=4^2[/tex]

[tex]\\ \rm\Rrightarrow x=4.0M[/tex]
