Dear Professor,

Is it right to say that the ICE method discusses the partial pressures of each type of gas?

I, standing for "Initial Pressure," C, standing for "Change in Pressure," and E, standing for "Equilibrium Pressure?"

I love the ICE method...makes it so much easier to break down the problem, and work towards a solution. Great teaching, Professor!

In example 3, we ignored the existence of the solid ammonium chloride in the flask when it came time to consider pressure.

I'm having trouble understanding that. According to the ideal gas law, pressure is dependent on the volume of the flask. So even if the solids are not directly contributing to the pressure of the gas wouldn't the space they are occupying restrict the volume available to the gases and so, affect the pressure?

Thank you.

Joseph
