Question

${SO}_2$ react with $O_2$ as follows :

${2SO}_2+O_2\to {2SO}_3$

The rate of disappearance of ${SO}_2$ is $2.4\times {10}^{-4}$ mol ${lit}^{-1}{min}^{-1}$, then :

• A. Rate of reaction is $1.2\times {10}^{-4}mole{lit}^{-1}{min}^{-1}$
• B. Rate of appearance of ${SO}_3$ is $2.4\times {10}^{-4}{molelit}^{-1}mi{n}^{-1}$
• C. Rate of disappearance of $O_2$ is $1.2\times {10}^{-4}{molelit}^{-1}mi{n}^{-1}$
• D. Rate of reaction is twice the rate of disappearance of ${SO}_2$

Answer 1

Answer: (B), (C)

The correct options are
B Rate of appearance of ${SO}_3$ is $2.4\times {10}^{-4}{molelit}^{-1}mi{n}^{-1}$
C Rate of disappearance of $O_2$ is $1.2\times {10}^{-4}{molelit}^{-1}mi{n}^{-1}$
