Calculate Kc for the reaction below if the concentration at equilibrium of the species are as given. [NOCl]=5103,[NO]=2.5103 and [Cl2]=2103. 2NOCl(g)2NO(g)+Cl2(g) For the reaction in Problem 7 the Kc=5.61012 at 400K. A mixture has a concentration of I2=.02M and a concentration of I=2108. Is the reaction at equilibrium, yes or no If it is not at equilibrium which direction does it have to shift to get to equilibrium, left or right? A reaction has an activation energy of 1105 joules at 25 degrees C. The Arrhenius factor A=1.0/sec and R=8.31J/mol. What is the value of the rate constant k in units of mol/sec?[A]
