Equilibrium Problems

8. Consider the reaction represented by the equation For the system at chemical equilibrium, which of the following explains what happens aft the volume of the reaction mixture is increased (assume constant temperature)? The amount of SO3(g) Increases and the value for K increases. The amount of SO3(g) decreases and the value for K increases. The amount of SO3(g) stays the same and the value for K decreases. The amount of SO3(g) decreases and the value for K stays the same. The amount of SO3(g) Increases and the value for K stays the same 9. Calculate the pH of a 0.050 M NaOH (a strong base) solution. -1.30 1.30 12.7 15.3 None of above.

Explanation / Answer

a)you marked it correctly,
the equilibrium shifts to the side which has lower no. of moles , if u are increasing the vlume.

b) pH = 14 + log(0.05) =12.69~12.7
