What is the ∆S of N₂(g) + 3H₂(g) ---> 2NH₃(g)?

Given

N₂(g)

(J/mol x K) = 191.5

H₂(g)

(J/mol x K) = 130.6

NH₃(g)

(J/mol x K) = 192.3

What is the total entropy change for the decomposition of hydrogen peroxide.

2H₂O₂(l) ---> 2H₂O(l) + O₂(g)

Given

H₂O₂(l)

(J/mol x K) = 109.6

(kJ/mol) = -187.8

H₂O(l)

(J/mol x K) = 69.9

(kJ/mol) = -285.8

O₂(g)

(J/mol x K) = 205.0

(kJ/mol) = 0
