The rate of a certain chemical reaction is directly proportional to the square of the concentration of chemical A present and in

motikmotik

Answer:

D. 40 % increase

Step-by-step explanation:

r = k[A]²/[B]

The rate is inversely proportional to [B]. If [B] is doubled, the rate is halved.

We must double this rate to get back to the original.

The rate is directly proportional to [A]².

2 = [A]₂/[A]₁² Take the square root of each side

√2 = [A]₂/[A]₁ Multiply each side by [A]₁

[A]₂ = √2[A]₁

[A]₂ = 1.41[A]₁

We must increase [A] by 41 %.

Monobromination of toluene gives a mixture of three bromotoluene products. Draw and name them.

Art [367]

Answer:

o-bromotoluene, m-bromotoluene and p-bromotoluene.

Explanation:

Hello,

In this case, on the attached picture you will find the reaction which yields o-bromotoluene as the first product, m-bromotoluene as the second product and p-bromotoluene as the last one since the substitution could be done at the second (ortho), third (meta) or fourth (para) carbons on the toluene.

Regards.
