Answer
Order: a, b, c
Work Step by Step
Recall, the greater the value of k, the more product-favored the reaction is. Using this, we get the order: $a, b, c$. In addition, if k is greater than one, the reaction is product-favored, while if it is less than one, the reaction is reactant favored. Using this, we find:
a) Reactant favored
b) Product favored
c) Product favored
