A quantity of HI was sealed in a tube, heated to 425 °C, and held at this temperature until equilibrium was reached. The concentration in the tube at equilibrium was found to be 0.0706 mol/L for HI, and 0.00955 mol/L for H2 and for I2. Calculate the Keq for the gas-phase reaction

At a certain temperature, the equilibrium constant, Kc, for thisreaction is 53.3.

H2(gas)+I2 ?2HI

At this temperature, 0.400 mol of H2 and 0.400 mol of I2 wereplaced in a 1.00-L container to react. What concentration of HI ispresent at equilibrium?

The equilibrium constant for HI decomposition at 500 °C is5.8×10-3.

2HI(g) = H2(g) + I2(g)

At that temperature reactants and products are gaseous. (There isno change in the total number of moles, so Kc = Kp.)
A sample of 0.29 mol of HI is placed in a 1.00 L vessel which isthen heated to 500 °C. When equilibrium is reached, what is themolar concentration of I2? (Give units)

At a certain temperature, the equilibrium constant, Kc, for this reaction is 53.3.
