on homework 5J5 b, why does the reactant change when there are same # of mols of both sides of equation?

Notice that C is a solid. Therefore the concentration of C won't change. Then, if you look at the equation again, there are more moles of gas on the products side than the reactants. This is why the reaction will favor the reactants side if you increase the pressure.

Solids and liquids do not have concentrations because their atoms are already as condensed as possible.

Yep. Just to add on, the only things in a reaction you have to worry about when we're calculating K values are the gases and aqueous solutions.
