A mixture of `1.57` mol of `N_(2)`, `1.92` mol of `H_(2)` and `8.13` mol of `NH_(3)` is introduced into a `20L` reaction vessel at `500K`. At this temperature, the equilibrium constant, `K_(c)` for the reaction `N_(2)(g)+3H_(2)(g)hArr2NH_(3)(g)` is `1.7xx10^(2)`. Is the reaction mixture at equilibrium ? If not, what is the direction of the net reaction ?
