Sulfonation of benzene has the following mechanism:(b) Write the overall rate law in terms of the initial rate of the reaction.

erica [24]

The overall rate law in terms of the initial rate of the reaction is:

= $k_{overall} [H_{2} SO_{4} ]^{2} [C_{6}H_{6}]$

The Sulfonation of benzene has the following mechanism:

(1) $2H_{2} SO_{4}$ ⇌ $H_{3}O^{+} + HSO_{4} + SO_{3}$

[fast]

(2) $SO_{3} + C_{6} H_{6}$ → $H(C_{6} H_{5}^{+} )SO_{3}^{-}$

[slow]

(3) $H(C_{6} H_{5}^{+} )SO_{3}^{-}$ $+ HSO_{4}^{-}$ → $C_{6} H_{5} SO_{3}^{-} + H_{2} SO_{4}$

[fast]

(4) $C_{6} H_{5} SO_{3}^{-} + H_{3}O^{+}$ → $C_{6} H_{5} SO_{3} H + H_{2} O$

[fast]

<h3>Calculation of rate law:</h3>

Given that the reaction's slowest step is the rate-dependent step, the following is the definition of rate law:

Rate = $k_{2} [SO_{3} ][C_{6} H_{6} ]$

However, the issue is that because $SO_{3}$ is an intermediate, it cannot be accounted for in the general rate legislation.

The following rate rule governs the synthesis of $SO_{3}$ :

Rate = $k_{1}[H_{2} SO_{4} ]^{2}$

Consequently, if we replace equation 1 with equation 2,

Rate is determined to be = $k_{overall} [H_{2} SO_{4} ]^{2} [C_{6}H_{6}]$

Hence, the overall rate law in terms of the initial rate of the reaction is:

= $k_{overall} [H_{2} SO_{4} ]^{2} [C_{6}H_{6}]$

In an experiment to determine the % of ascorbic acid in Vitamin C Tablets by Titration with Potassium Bromate,

answer:

Oxidation half reaction of Vitamin C

Explanation:

The solution will turn cloudy dark purple even after reaching endpoint when allowed to settle with time. because of the Oxidation half reaction of Vitamin C. also during the Titration process few drops of starch solution will be added to help determine the endpoint of the experiment .

How is the enthalpy of reaction shown in this potential energy diagram?

Snowcat [4.5K]

Answer : The correct option is C.

Explanation :

Enthalpy of reaction : It is defined as the changes in heat energy takes place when reactants go to products. It is denotes as $\Delta H$ .

$\Delta H$ = Energy of product - Energy of reactant

$\Delta H$ is positive when heat is absorbed and the reaction is endothermic.

$\Delta H$ is negative when heat is released and the reaction is exothermic.

In the given potential energy diagram, the energy of product at higher level and energy of reactant at lower level. The $\Delta H$ for this reaction will be positive.

So, the enthalpy of reaction is defined as the difference of the energy of the reactants and the energy of the products.
