Sodium reacts violently with water according to the equation:

2 Na(s) + 2 H_{2}O(l) →2NaOH(aq) + H_{2}(g)

The resulting solution has a higher temperature than the water prior to the addition of sodium. What are the signs of ΔH°and ΔS° for this reaction?

a. ΔH° is negative and ΔS° is positive.

b. ΔH° is positive and ΔS° is negative.

c. ΔH° is negative and ΔS° is negative.

d, ΔH° is positive and ΔS° is positive.
