Answer :
(A) The rate expression will be:
(B) The average rate of the reaction during this time interval is, 0.00176 M/s
(C) The amount of Br₂ (in moles) formed is, 0.0396 mol
Explanation :
Rate of reaction : It is defined as the change in the concentration of any one of the reactants or products per unit time.
The given rate of reaction is,
The expression for rate of reaction :
<u>Part A:</u>
The rate expression will be:
<u>Part B:</u>
The average rate of the reaction during this time interval is, 0.00176 M/s
<u>Part C:</u>
As we are given that the volume of the reaction vessel is 1.50 L.
Now we have to determine the amount of Br₂ (in moles).
The amount of Br₂ (in moles) formed is, 0.0396 mol
