Answer:
The correct answer is : No, because there are 4 hydrogen atoms on the reactants side and 2 on the products side.
Explanation:
The given reaction equation is not balanced because:
- Number of hydrogen atoms on both sides are not equal that is 4 on reactants side and 2 on products side.
- Number of oxygen atoms on both sides are not equal that is 3 on reactants side and 2 on products side.
In a balanced chemical equation number of atoms of each elements are equal on both sides.
So, the balanced chemical equation will be:
Question is incomplete, complete question is as follows :
Complete Question : .Sulfonation of benzene has the following mechanism:
(1) 2 H2SO4 ⇌ H3O+ + HSO4− + SO3
[fast]
(2) SO3 + C6H6 → H(C6H5+)SO3−
[slow]
(3) H(C6H5+)SO3− + HSO4− → C6H5SO3− + H2SO4
[fast]
(4) C6H5SO3− + H3O+ → C6H5SO3H + H2O
[fast]
write the overall rate law for the initial rate of the reaction as a fraction.
Rate=k(________/_________)
Answer:
The overall rate law for the initial reaction is =
Explanation :
Frist of all, all the common terms are cancelled out and written the overall reaction.
As we know that the rate depednant step is the slowest step of the reaction, rate law is :
rate =
But the problem is that SO3 cannot be written in the overall rate law because it is an intermediate.
Rate law for synthesis of S03 is as follows :
rate =
Hence when we substitute equation 2 in equation one,
Rate comes out to be =
