1. The equilibrium system shown below has a K = 8.3 x 10 power(-2). If [D] = 0.38 mol/L, what is the [A]?
2A(g) + B(s) <===> C(s) + 3D(g)
2. Sodium hydroxide (lye) is a common component of oven cleaners. Calculate the pH of the solution that results when 24.00 g oh NaOH are dissolved in enough water to make 750ml of cleaning solution.
3. Predict the shift in equilibrium that takes place if the volume is decreased, and explain why the equilibrium shifts in that direction.
H2CO3(aq) + energy <==> CO2(g) + H2O (l)
4. At 460 degrees Celsius, the reaction SO2(g) + NO2(g) <==> NO(g) + SO3(g)
has K = 85.0. A reaction flask contains these gases at the following concentrations: [SO2] = 0.00150 mol/L.. [NO2] = 0.00300 mol/L...[NO] = 0.0100 mol/L...[SO3] = 0.0400 mol/L. Show that this system is not at equilibrium, and determine the direction in which the reaction must procedd to reach equilibrium.
5. What is the pH of a 0.47 mol/L solution of acetic acid ( CH3COOH), a weak acid) if its Ka = 1.8 x 10power(-5) ?
