draw particle diagrams that account for the fact that 2 volumes of nitric oxide gas react with 1 volume of oxygen gas to form 2 volumes of product with no leftover gas
To draw particle diagrams that account for the given reaction, we need to understand the stoichiometry of the reaction and the behavior of gas particles.
The balanced equation for the reaction is:
2 NO(g) + O2(g) -> 2 NO2(g)
According to the stoichiometry, 2 volumes of nitric oxide gas react with 1 volume of oxygen gas to form 2 volumes of nitrogen dioxide gas. Let's break down this reaction step by step:
Step 1: Start with 2 volumes of nitric oxide (NO) gas.
We can draw two particles representing the NO gas. Each particle will be labeled as NO.
NO NO
Step 2: Next, add 1 volume of oxygen gas (O2).
Oxygen gas is diatomic, which means it exists as O2 molecules. So we need to draw two oxygen particles.
NO NO O2 O2
Step 3: During the reaction, the oxygen gas molecules (O2) will break apart into individual oxygen atoms (O). Therefore, we need to split the O2 particles into separate O particles. Each O2 particle will be replaced by two individual O particles.
NO NO O O O O
Step 4: Now, the nitric oxide (NO) gas will react with the oxygen (O) particles. Each NO molecule will react with one O atom to form nitrogen dioxide (NO2) molecule.
NO NO O O O O
------>
NO2 NO2
Step 5: Finally, we need to account for the fact that 2 volumes of nitrogen dioxide (NO2) gas are produced. Therefore, each NO2 molecule will be represented by two NO2 particles.
NO NO O O O O
------>
NO2 NO2 NO2 NO2
In the final diagram, we have accounted for the fact that 2 volumes of NO react with 1 volume of O2 gas to form 2 volumes of NO2 gas.
