Answer to Question #259620 in Inorganic Chemistry for s2pid

Question

A closed system initially containing 1.000 × 10-3 M H2 and 2.000 × 10-3 M I2 at 448°C is allowed to reach

equilibrium.At equilibrium, the HI concentration is 1.87 × 10-3 M. Given that the reaction equation is H2(g) + I2(g)

↔ 2 HI(g), find:

a. Equilibrium concentrations of the two reactants

b. Kc of the reaction taking place.

Answer 1

1.00×10^-3/2.00×10^-3

= 0.5
