What is the equilibrium constant expression for the following reaction?

Zanzabum

Answer:

Keq = [CO][Cl₂]/[COCl₂].

Explanation:

For the balanced reaction:

COCl₂(g) ⇄ CO(g) + Cl₂(g).

The equilibrium constant can be expressed as concentration equilibrium constant (Kc) or pressure equilibrium constant (Kp).

The equilibrium constant is the ratio of the product of products concentrations to the product of the reactants concentrations.

Keq = [CO][Cl₂]/[COCl].

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:

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