Question

The reaction, ⇌ $2 \mathrm { SO } _ { 3 ( g ) }$ is carried out in a 1$d m ^ { 3 }$vessel and $2 \mathrm { dm } ^ { 3 }$ vessel separately. The ratio of the reaction velocities will be.

• A. $1 : 8$
• B.
• C. $4 : 1$
• D. $8 : 1$

Answer 1

Answer: (D)

$8 : 1$

Answer 2

$2 \mathrm { SO } _ { 2 } ( g ) + O _ { 2 } ( g )$ ⇌

For $R = k \left[ \mathrm { SO } _ { 2 } \right] ^ { 2 } \left[ O _ { 2 } \right]$

$R = K \left[ \frac { 1 } { T } \right] ^ { 2 } \left[ \frac { 1 } { 1 } \right] = 1$

For $2 d m ^ { 3 }$ $R = K \left[ \frac { 1 } { 2 } \right] ^ { 2 } \left[ \frac { 1 } { 2 } \right] = \frac { 1 } { 8 }$

So, the ratio is 8 : 1
