Question

Average rate of reaction for the following reaction.

\[\ce{2SO2 (g) + O2(g) -> 2SO3 (g)}\] is written as ______.

विकल्प

• `(Delta ["SO"_2])/(Delta"t")`

• - `(Delta ["O"_2])/(Delta"t")`

• `1/2 (Delta ["SO"_2])/(Delta"t")`

• `(Delta ["SO"_3])/(Delta"t")`

Answer 1

\[\ce{2SO2 (g) + O2(g) -> 2SO3 (g)}\] is written as `underline((Delta ["O"_2])/(Delta"t"))`.

Explanation:

For reaction, \[\ce{2SO2 (g) + O2(g) -> 2SO3 (g)}\]

`- 1/2 (Delta ["SO"_2])/(Delta "t") = (- Delta ["O"_2])/(Delta"t") = + 1/2 (Delta ["SO"_3])/(Delta "t")`

So, average rate of reaction is written as - `(Delta ["O"_2])/(Delta"t")`.
