Interpretation Introduction

Interpretation:

Imidazole, pyrrole and benzene are should be ranked from most reactive to least reactive in the electrophilic aromatic substitution.

Concept Introduction:

Aromatic compounds such as benzene which is having closed ring and alternate double bonds undergo electrophilic aromatic substitution reactions. Electrophilic aromatic substitution takes place when an electrophile displaces a hydrogen atom of an aromatic ring. There are five most common electrophilic aromatic substitution reactions that are halogenation, nitration, sulfonation, Friedel-Crafts acylation and Friedel-Crafts alkylation. All these reactions take place by same two-step mechanism.

Consider the following chemical equilibrium: 2SO2(g) + O2(g) = 2SO3(g) • Write the equilibrium constant expression for this reaction. Now compare it to the equilibrium constant expression for the related reaction: • . 1 SO2(g) + O2(g) = SO3(g) 2 How do these two equilibrium expressions differ? What important principle about the dependence of equilibrium constants on the stoichiometry of a reaction can you learn from this comparison?
Given Kp for 2 reactions. Find the Kp for the following reaction: BrCl(g)+ 1/2 I2(g) ->IBr(g) + 1/2 Cl2(g)
For a certain gas-phase reaction at constant pressure, the equilibrium constant Kp is observed to double when the temperature increases from 300 K to 400 K. Calculate the enthalpy change of the reaction, Ah, using this information.
