Consider the following system at equilibrium where $\Delta H^\circ = -111$ kJ, and $K_c = 0.159$, at 723 K: $N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)$ When 0.16 moles of $H_2(g)$ are added to the equilibrium system at constant temperature: The value of $K_c$ increases decreases remains the same The value of $Q_c$ is greater than $K_c$ is equal to $K_c$ is less than $K_c$ The reaction must run in the forward direction to reestablish equilibrium run in the reverse direction to reestablish equilibrium remain in the current position, since it is already at equilibrium The concentration of $N_2$ will increase decrease remain the same
