Re: Entropy and Reduction in moles of Gas
When there are less mols of gas, that means there are less molecules to add to the disorder that contributes to entropy.

Re: state functions
This is because it's dependent on the pressure and volume, meaning it can't be a constant value like with a state function.

Re: Steam vs Boiling Water
There is more energy in steam, since the energy in boiling water tops out at 100 degrees Celsius as it is going through the phase change.

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.
