Hey there Kimberly!
In this problem you have to figure out the signs of change in entropy, remembering that increase in moles of gas is increase in entropy so it is positive, while decrease in moles of gas is decrease in entropy and is negative.
Also, using this awesomely helpful punnet square which tells you the spontaneity of a reaction, you are able to determine if a certain reaction is spon, and if it is, it will be favoring products. If a reaction is nonspon, then it will be favoring reactants. For those instances where we are not sure if rxn is spon or not because it requires higher or lower temp, we can not determine.
Let us know if you have any more questions about this.
