Answer to Question #192291 in Organic Chemistry for GHOST

Question #192291

a. The equilibrium constant Kc of the reaction: H2 (g) + I2 (g)  ˂˂˂˗˗˗˗˗˗˗˃˃˃˃  HI (g) is 54.3 at 430 oC. Starting with 6.0 moles of HI in a 1.0 dm-3 reaction vessel.

i. Calculate the concentrations of H2 (g), I2 (g) and HI (g) at equilibrium.

ii. If H2 (g) is added  to the reaction vessel to increase its concentration to 2.0 M, determine the reaction quotient Q, then calculate the concentration of all the gases when the new equilibrium is re-established.
