Magnesium reacts with nitrogen to form magnesium nitride. The chemical formula for this reaction is Mg + N2 MgN2. What is the pr
2 answers:
Answer:
The product of this reaction is C. magnesium nitride
Explanation:
First of all, the chemical formula for this reaction is wrong. It should be :
⇒
(I)
When we have a chemical reaction, for example :
⇒
The substances A and B are called the reactants.
The substance C is called the product.
In a chemical reaction there could be one or more reactants and one or more products.
In the equation (I) the magnesium nitride is in the products side.
Therefore, in the chemical reaction of magnesium and nitrogen the magnesium nitride is the product.
The correct option is C. magnesium nitride

Answer:
b. Second order in NO and first order in O₂.
Explanation:
A. The mechanism
B. The rate expressions
The last expression is the rate law for the slow step. However, it contains the intermediate N₂O₂, so it can't be the final answer.
C. Assume the first step is an equilibrium
If the first step is an equilibrium, the rates of the forward and reverse reactions are equal. The equilibrium is only slightly perturbed by the slow leaking away of N₂O₂ to form product.
D. Substitute this concentration into the rate law
The reaction is second order in NO and first order in O₂.
