The following reaction takes place in one step:
How will the rate of the above reaction change if the volume of the reaction vessel is diminished to one-third of its original volume? Will there be any change in the order of the reaction with the reduced volume?
How will the rate of the above reaction change if the volume of the reaction vessel is diminished to one-third of its original volume? Will there be any change in the order of the reaction with the reduced volume?
Answer: Rate becomes 27 times; order (= 3) is unchanged.
Solution
The reaction occurs in one step (elementary), so
Reducing the volume to one-third makes every concentration three times larger:
The order depends only on the rate law, not on concentrations — it remains 3.
Reducing the volume to one-third makes every concentration three times larger:
The order depends only on the rate law, not on concentrations — it remains 3.
