Question

06. Consider the following binding energies in Kj/mol: O - H...460; H -H...436 O=O...490. calculate the Δ H of the reaction represented by: 2 H₂O(g) → 2 H₂(g) + O₂(g) *

a) - 442 Kj
b) + 478 Kj
c) + 442 Kj
d) - 478 Kj
e) + 3202 Kj

help, pls

Answer 1

Explanation:

Chemistry

Calculate ΔH

o

for the reaction,

Na

2

O(s)+SO

3

(g)→Na

2

SO

4

(g) using the following :

Na(s)+H

2

O(l)→NaOH(s)+

(g);ΔH

o

=−146kJ

Na

2

SO

4

(s)+H

2

O(l)→2NaOH(s)+SO

3

(g);ΔH

o

=+418kJ

2NaO(s)+2H

2

(g)→4Na(s)+2H

2

O(l);ΔH

o

=+259kJ
