• A. $\mathrm { N } _ { 2 } ( \mathrm {~g} ) + 3 \mathrm { H } _ { 2 } ( \mathrm {~g} ) \xrightarrow { \mathrm { Fe } } 2 \mathrm { NH } _ { 3 } ( \mathrm {~g} )$
• B.
• C.
• D. $2 \mathrm { SO } _ { 2 } ( \mathrm {~g} ) + \mathrm { O } _ { 2 } ( \mathrm {~g} ) \xrightarrow { \mathrm { V } _ { 2 } \mathrm { O } _ { 5 } } 2 \mathrm { SO } _ { 3 } ( \mathrm {~g} )$
