Chapter 14, Problem 14.19P

PRACTICE 14.19 Calculate the equilibrium concentrations of H2, I₂, and HI at 700 K if the initial concentrations are [H₂] = 0.100 M and [I₂] = 0.300 M. The equilibrium constant K_C for the reaction ${\text{H}}_{\text{2}}\left(g\right)+{\text{I}}_{\text{2}}\left(g\right)\rightleftarrows 2\text{HI}\left(g\right)$ is 57.0 at 700 K.
