Answer to Question #204807 in General Chemistry for Jake

Question

4)

Given: 2X(g) ⇌ Y(g) + Z(g) Ke = 15

If 2.0 mol of Y and 2.0 mol of Z are injected into an empty 4.0 L container, then find the resulting

equilibrium concentration of X.

also need help with this

Answer 1

$K_c=Q_c=$ $[x]^2\over[y][x]$

$x=$ $\sqrt{(15.0)(2.0mol)(2.0mol)}\over4.0L$

$x=$ $\sqrt{60}\over 4$

$x=$ $3.873mol/L$
