Homework Answers
a) If product predominates that means forward reaction takes place.
In this case Q<K , value of Q will be less than one
b) if Q is less than 1 then lnQ will be negative
c) lnQ is negative 
so 
is negative
which tells us that the reaction will go to the forward direction.
and the reaction will be feasible.
