Consider the mechanism. Step 1: 2 A ⟶ B + C slow Step 2: B + C ⟶ E fast Overall: 2 A ⟶ E Determine the rate law for the overall reaction, where the overall rate constant is represented as k .

rate = k[A]²

Explanation:

Two principles:

Step 1: 2A ⟶ B + C (slow)  

Step 2: B + C ⟶ E (fast)  

Overall: 2A ⟶ E

The rate law for the reaction is the same as that for Step 1:

rate = k[A]²

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

the answer would be b i believe
