PLEASE ANSWER ALL THREE QUESTIONS, WITH BOTH PARTS.

Consider the following reaction where Kc=0.00650 at 298K. 2NOBr(g)2NO(g)+Br2(g) A reaction mixture was found to contain 0.0873 moles of NOBr(g),0.0282 moles of NO(g), and 0.0393molesofBr(g), in a 1.00 liter container. Calculate Qc. Qc= Is the reaction at equilibrium? If not, what direction must it run in order to reach equilibrium? The reaction must run in the forward direction to reach equilibrium. The reaction must run in the reverse direction to reach equilibrium. The reaction is at equilibrium. Consider the following reaction where KC=55.6 at 698K. H2(g)+I2(g)2HI(g) A reaction mixture was found to contain 2.86102 moles of H2(g),3.94102 moles of I2(g) and 0.292moles of HI(g), in a 1.00 liter container. Is the reaction at equilibrium? If not, what direction must it run in order to reach equilibrium? The reaction quotient, QC equals The reaction A. must run in the forward direction to reach equilibrium. B. must run in the reverse direction to reach equilibrium. C. is at equilibrium. Consider the following reaction where Kc=1.80104 at 298K. NH4HS(s)NH3(g)+H2S(g) A reaction mixture was found to contain 0.0516 moles of NH4HS(s),0.0176 moles of NH3(g), and 0.0134 moles of H2S(g), in a 1.00 liter container. Is the reaction at equilibrium? If not, what direction must it run in order to reach equilibrium? The reaction quotient, Qc, equals The reaction must run in the forward direction to reach equilibrium. must run in the reverse direction to reach equilibrium. is at equilibrium
