When there are less mols of gas, that means there are less molecules to add to the disorder that contributes to entropy.

Re: K value

K=1 is rare because K is the ratio of reactants to products. If K was 1, that would mean that there is an equal amount of products to reactants.

Re: ICE Table

To find initial, you take the number of mols given to you and divided it by the volume since concentration is n/v. For initial you take your initial concentration and subtract it from x, x being what we are trying to find in the problem.
