Anomalous Behavior of Lithium Halogens

Question

It may be noted that lithium has most negative $E^{Θ}$ value (table 9.1). But its reaction with water is less vigorous than that of sodium which has the least negative $E^{Θ}$ value among the alkali metals. This behaviour of lithium is attributed to its small size and very high hydration energy. Other metals of the group react explosively with water.
