Consider the following reaction: A(g)⇌B(g)+C(g) Find the equilibrium concentrations of A, B, and C for each of the following different values of Kc. Assume that the initial concentration of A in each case is 1.0 M and that the reaction mixture initially contains no products. Make any appropriate simplifying assumptions. Part A Kc= 1.8 Express your answer using two significant figures. Enter your answers numerically separated by commas. [A][ A ], [B], [C] = nothing M
A (g) B(g) + C(g)
ICE table is
[A] | [B] | [C] | |
Initial | 1.0 | 0 | 0 |
Change | -x | +x | +x |
Equilibrium | (1.0-x) | x | X |
Kc =
Or, 1.8 =
Or, 1.8(1-x) = x2
Or, 1.8 - 1.8x = x2.
Or, x2 +1.8x -1.8 = 0
Using solve for quadratic equation.
X =
a = 1 , b = 1.8 , c = -1.8
X =
Or, x =
Or, x = 0.715 or, X = - 2.515
Final molarity cannot be negative.
Hence, x = 0.715 M.
So, [A] = (1.0 - 0.715) = 0.285 M = 0.28 M ( 2 significant figure)
[B] = 0.715 M = 0.72 M ( 2 significant figure)
[C] = 0.715 M = 0.72 M ( 2 significant figure)
[Putiing the value un expression of Kc
Kc = = 1.8
Hence answer is correct.]
