At 584 degree celcius,Kc=65.0 for the reaction 2HI= I2 + H2. The following concentrations were detected in a mixture, concentration of HI= 0.500M, concentration of H2= 2.80M and concentration of I2 =3.40M. (i) Is the system in equilibrium? If not, which direction must the reaction proceed for equilibrium to be established? (ii) What is the Kp for this system at equilibrium?
