Is a bimolecular reaction necessarily second-order? Is a second-order reaction necessarily bimolecular? Answer, with explanation
Kruka [31]
A bimolecular reaction is always a second-order reaction, but a second-order reaction is not always a bimolecular reaction.

The most important thing to take note of is that molecularity of a reaction is a concept applicable to only elementary reactions, meaning non-complex. In a way, elementary reactions are basic and achieved in one step. Complex reactions involve intermediate steps before achieving the desired reaction.

Molecularity is equal to the sum of the coefficients of the reactants, so two reactants give a second-order bimolecular reaction. However, second-order reactions can involve more than two reactants especially in complex reactions.

Write the formula for a complex formed between zn2 zn2 and nh3nh3 with a coordination number of 3.
fredd [130]

Triammine zinc sulfate is the formula for a compound produced between zn2 and nh3 with a coordination number of 3.

<h3>Steps</h3>

Zinc atoms are present in the +2 oxidation state in zinc sulfate (ZnSO4).

Thus, a coordination complex formed by three ammonia ligands and zinc sulfate can be shown below.

NH3 + ZnSO4 = [Zn(NH3)] SO4

In its ionic form, this equation can be expressed as

Zn²⁺ + 3NH₃ = [Zn(NH₃)₃]²⁺

<h3>Coordination number: what is it?</h3>

The number of atoms, ions, or molecules that a central atom or ion in a complex, coordination compound, or crystal holds as its closest neighbors.

<h3>What is a good illustration of a coordination number?</h3>

For instance, [Cr(NH3)2Cl2Br2] has the core cation Cr3+, which is referred to as hexacoordinate and has a coordination number of 6.

Is Cu^2+ + 2Br^- --&gt; Cu + Br2 a spontaneous or non-spontaneous redox reaction?
lawyer [7]

The reaction above is a spontaneous reaction

Cu^2+ + 2Br^- --> Cu + Br2

<h3>What is spontaneous redox reaction?</h3>

A spontaneous redox reaction is a special type of redox reaction which involves the release of energy where the electrons are transferred from from an anode to the cathode

General spontaneous redox reactions is found mostly in electrochemical cells

So therefore, the reaction above is a spontaneous reaction.

Cu^2+ + 2Br^- --> Cu + Br2
