Keq and ICE chart Assignment

1) 0.463 mol/L of HI(g) is placed in a 1.00 L reaction vessel. The temperature is raised

to 300Ε°C and maintained until equilibrium is established. At equilibrium, the vessel

contains 0.119 mol/L of hydrogen gas and 0.119 mol/L iodine gas. Are the reactants

or the products favoured? Justify your answer by your Keq value.

2) Initial concentrations of H

and Cl

in a flask were 0.576 mol/L. The mixture was

2(g)

allowed to reach equilibrium at 45°C. The equilibrium concentration of HCl(g) was

found to be 0.356 mol/L. Calculate the equilibrium concentrations of the reactants.

3) At high temperatures, nitrogen and oxygen gases react to produce nitrogen monoxide.

Calculate the equilibrium concentration of nitrogen monoxide if the equilibrium

-4

concentrations of oxygen and nitrogen are 0.457 mol/L and K is 1.3x10

at 1800 K.

4) Consider the following reaction 2 NO (g) + 2 H

(g) N

(g) + 2 H

O (g) Determine

the value of the equilibrium constant, Kc, for the reaction. Initially, a mixture of

0.100 M NO, 0.050 M H

, 0.100 M H

O was allowed to reach equilibrium (initially

there was no N2). At equilibrium the concentration of NO was found to be 0.062 M.
