Question: Which of the following is an example of homogeneous equilibrium?...

Which of the following is an example of homogeneous equilibrium?

A

2SO2( g)+O2( g)2 \mathrm { SO } _ { 2 ( \mathrm {~g} ) } + \mathrm { O } _ { 2 ( \mathrm {~g} ) } 2SO3( g)2 \mathrm { SO } _ { 3 ( \mathrm {~g} ) }

B

C(s)+H2O(g)\mathrm { C } _ { ( \mathrm { s } ) } + \mathrm { H } _ { 2 } \mathrm { O } _ { ( \mathrm { g } ) } CO(g)+H2( g)\mathrm { CO } _ { ( \mathrm { g } ) } + \mathrm { H } _ { 2 ( \mathrm {~g} ) }

C

CaCO3( s)\mathrm { CaCO } _ { 3 ( \mathrm {~s} ) } CaO(s)+CO2( g)\mathrm { CaO } _ { ( \mathrm { s } ) } + \mathrm { CO } _ { 2 ( \mathrm {~g} ) }

D

NH4HS(s)\mathrm { NH } _ { 4 } \mathrm { HS } _ { ( \mathrm { s } ) } NH3( g)+H2 S(g)\mathrm { NH } _ { 3 ( \mathrm {~g} ) } + \mathrm { H } _ { 2 } \mathrm {~S} _ { ( \mathrm { g } ) }

Answer

2SO2( g)+O2( g)2 \mathrm { SO } _ { 2 ( \mathrm {~g} ) } + \mathrm { O } _ { 2 ( \mathrm {~g} ) } 2SO3( g)2 \mathrm { SO } _ { 3 ( \mathrm {~g} ) }
