Answer to Question #171262 in General Chemistry for Leslie

Question

For the reaction  2A(g) ⇌ 2B(g) + C(g),  K_c = 1.20 x10⁻⁷ at a given temperature.

If the initial concentration of A in a closed container is 0.610 M, what is the approximate equilibrium concentration of B?

Answer 1

1.2 x 10^-7 = x * 0.5x/0.61

x= 0,00054110997

B= 0,00054110997
