Sodium reacts violently with water according to the equation:
2 Na(s) + 2 H2O(l) →2NaOH(aq) + H2(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.
