1) A suggested mechanism for the reaction of nitrogen dioxide and molecular fluorine is:
$$
\begin{array}{ll}
N O 2(g)+F 2(g) \rightarrow N O 2 F(g)+F(g) & \text { Step 1 } \
N O 2(g)+F(g) \rightarrow N O 2 F(g) & \text { Step 2 }
\end{array}
$$
a. Write the equation for the overall reaction and identify the reaction intermediates
b. What is the molecularity of each of the elementary reactions?
$[F(\mathrm{~g})$ is intermediate; both steps bi-molecular]

Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Determine the overall reaction**: To find the overall reaction, we need to add the two steps of the mechanism and cancel out any intermediates that appear on both sides of the reaction. ‖ ‖ 2 ⋮ **Identify intermediates**: Intermediates are species that are produced in one step of a reaction mechanism and consumed in a subsequent step. They do not appear in the overall reaction. ‖ ‖ 3 ⋮ **Write the overall reaction**: Adding the two steps and canceling the intermediate $F(g)$, we get the overall reaction: $2 NO_2(g) + F_2(g) \rightarrow 2 NO_2F(g)$. ‖ ∻1 Answer∻ ⚹ The overall reaction is $2 NO_2(g) + F_2(g) \rightarrow 2 NO_2F(g)$, and the reaction intermediate is $F(g)$. ⚹ ∻Key Concept∻ ⚹ Overall reaction and intermediates ⚹ ∻Explanation∻ ⚹ The overall reaction is obtained by summing the steps of the mechanism and canceling out the intermediates, which are species that appear in the mechanism but not in the overall reaction. ⚹ ∻Solution∻ ‖ 1 ⋮ **Analyze Step 1**: The molecularity of a reaction is the number of reactant particles involved in an elementary step. ‖ ‖ 2 ⋮ **Analyze Step 2**: Similarly, we determine the molecularity of the second step by looking at the number of reactant particles involved. ‖ ‖ 3 ⋮ **Determine molecularity**: Since both steps involve two reactant particles, both steps are bimolecular. ‖ ∻2 Answer∻ ⚹ Both Step 1 and Step 2 are bimolecular. ⚹ ∻Key Concept∻ ⚹ Molecularity of a reaction ⚹ ∻Explanation∻ ⚹ Molecularity refers to the number of reactant particles involved in an elementary step, and both steps in the given mechanism are bimolecular because they each involve two reactant particles. ⚹◊What is the overall reaction equation for the reaction between nitrogen dioxide and molecular fluorine, considering the suggested two-step mechanism provided?⍭ Generate me a similar question◊
