Question

Which of the following reactions will not get affected on increasing the pressure?

• A. $2 \mathrm { H } _ { 2 ( \mathrm {~g} ) } + \mathrm { CO } _ { ( \mathrm { g } ) }$
• B. $4 \mathrm { NH } _ { 3 ( \mathrm {~g} ) } + 5 \mathrm { O } _ { 2 ( \mathrm {~g} ) }$ $4 \mathrm { NO } _ { ( \mathrm { g } ) } + 6 \mathrm { H } _ { 2 } \mathrm { O } _ { ( \mathrm { g } ) }$
• C. $\mathrm { CH } _ { 4 ( \mathrm {~g} ) } + 2 \mathrm {~S} _ { 2 ( \mathrm {~g} ) }$ $\mathrm { CS } _ { 2 ( \mathrm {~g} ) } + 2 \mathrm { H } _ { 2 } \mathrm {~S} _ { ( \mathrm { g } ) }$
• D.

Answer 1

Answer: (C)

$\mathrm { CH } _ { 4 ( \mathrm {~g} ) } + 2 \mathrm {~S} _ { 2 ( \mathrm {~g} ) }$ $\mathrm { CS } _ { 2 ( \mathrm {~g} ) } + 2 \mathrm { H } _ { 2 } \mathrm {~S} _ { ( \mathrm { g } ) }$

Answer 2

: Since number of moles of gaseous reactants and products are same, the reaction will not be affected by changing the pressure.
