Use one or two sentences to describe what “dynamic equilibrium” means to a chemist. Consider several ice cubes in equilibrium with cold water in a styrofoam cup. Write a chemical equation describing the equilibrium (with states of matter). Use a sentenec to describe any changes that might make this a “dynamic” equilibrium. What will the temperature of the water be at equilibrium? Write the simplest equilibrium constant, K c , for each reaction below: a) 3 O 2 ( g ) 2 O 3 ( g ) b) SiH 4 ( g ) + 2 O 2 ( g ) SiO 2 ( s ) + 2 H 2 O( g ) c) MgO( s ) + SO 2 ( g ) + ½ O 2 ( g ) MgSO 4 ( s ) d) 2 PbS( s ) + 3 O 2 ( g ) 2 PbO( s ) + 2 SO 2 ( g ) Write the simplest equilibrium constant, K p , (in terms of partial pressures) for reactions a and c from #3. The Haber-Bosch process enabled synthesis of ammonia by the following reaction: 3 H 2 ( g ) + N 2 ( g ) 2NH 3 ( g ) K c = 0.16 at 450 ºC Calculate the K p for this reaction (seek out appropriate constants and equations in text) 1. 2.
