Answer:
10%
Explanation:
The percent by volume of acetone is given by the following formula:
% v/v = Volume of acetone / Total Volume * 100%
Now we <u>calculate the total volume of the solution</u>:
Total Volume = Volume of Acetone + Volume of Water
Total Volume = 50 mL + 450 mL = 500 mL
Then we <u>calculate the percent by volume:</u>
% v/v = 50 mL / 500 mL * 100 % = 10%
Answer:
Koverall [NO]^2 [Br2]
Balanced chemical reaction equation;
2NO + Br2 ⇄2NOBr
Explanation:
Consider the first step in the reaction;
NO(g) + Br2(g) ⇄ NOBr2(g) fast
The second step is the slower rate determining step
NOBr2(g) + NO(g) ⇄ 2NOBr(g)
Given that k1= [NOBr2]/[NO] [Br2]
k2= [NOBr2] [NO]
The concentration of the intermediate is now;
[NOBr2]= k1[NO][Br2]
It then follows that overall rate of reaction is
Rate= k1k2[NO]^2 [Br2]
Since k1k2=Koverall
Rate= Koverall [NO]^2 [Br2]
