The bond enthalpy decreases down the group of group 17 elements as the size of the atom increases. As both H and F atoms have small size, hence are similar, they are able to form a stronger bond than say I and H. Hydration enthalpy of F is lower as the atom is smaller. Hence the bond enthalpy is most for H--F and hence the enthalpy of reaction is the highest. Hope this helps! cheers xx
