Consider the following system at equilibrium where H=111kJ/mol, and KC=6.30, at 723K. 2NH3(g)N2(g)+3H2(g) When 0.34 moles of NH3(g) are removed from the equilibrium system at constant temperature The value of Kc. The value of Qc The reaction must run in the forward direction to restablish equilibrium. run in the reverse direction to restablish equilibrium. remain the same. It is already at equilibrium. The concentration of N2 will Consider the following system at equillbrium where H=182kJ, and Kc=7.00105, at 673K. NH4I(s)NH3(g)+HI(g) When some moles of NH4I(s) are removed from the equilibrium system at constant temperature: The value of Kc increases decreases remains the same The value of Qc is greater than Kc is equal to Kc is less than Kc The reaction must run in the forward direction to reestablish equilibrium. run in the reverse direction to reestablish equilibrium. remain the same. It is already at equilibrium. The number of moles of NH3 will increase decrease remain the same
