Question

For the reaction 2HI(g) ⇌ H2(g) + I2(g), the Kc is equal to 0.020 at 720K. The initial concentrations of HI is 1.25 × 10-3 M, the initial concentration of H2 and I2 are 1.50 × 10-3 M. d. What are the final concentrations of all products and reactants at equilibrium? e. After equilibrium is reached, additional H2 is added to the reaction vessel, increasing the concentration of H2 to 0.500 M. What happens to the equilibrium?
