Question

ICS AND EQU Identifying intermediates in a reaction mechanism _ Consider the following mechanism for the formation of iodine: H2(g) + ICI(9) → HI(g) + HCI(g) (1) HI(g) + ICI(g) → 12(g) + HCl(g) (2) Write the chemical equation of the overall reaction: Are there any ○yes intermediates in this no mechanism? If there are intermediates, write down their chemical formulas. Put a comma between each chemical formula, if there's more than one. Check Explanation

Answer 1

Explanation:

Mechanism for the formation of iodine:

Step 1 :

$H_2(g) + ICI(g) \rightarrow HI(g) + HCI(g)$

Step 2 :

$HI(g) + ICI(g) \rightarrow I_2(g) + HCl(g)$

By adding both reaction we will get the overall reaction of formation of iodine:

$H_2(g)+2ICl(g)\rightarrow I_2(g)+2HCl(g)$

Intermediate are defined as short lived chemical species which are formed during the course of a chemical reaction. They are formed in one step and in an other step they serve as a reactant.

The intermediate formed between the course of mechanism : HI
