Chapter 6.5, Problem 6.13P

Identify the forward and reverse reactions in each of the following reversible reactions.

a. ${\text{2 SO}}_{\text{2}}\left(g\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)\stackrel{}{\rightleftarrows }{\text{ 2 SO}}_{\text{3}}\left(g\right)$

b. ${\text{N}}_{\text{2}}\left(g\right)+{\text{O}}_{\text{2}}\left(\text{g}\right)\stackrel{}{\rightleftarrows }\text{ 2 NO}\left(g\right)$

c. ${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}{\text{O}}_{\text{2}}\left(g\right)+{\text{CH}}_{\text{4}}\text{O}\left(\text{g}\right)\stackrel{}{\rightleftarrows }{\text{ C}}_{\text{3}}{\text{H}}_{\text{6}}{\text{O}}_{\text{2}}{\text{+ H}}_{\text{2}}\text{O}$
