Answer:
![r=-k[H_2][O_2]^{1/2}](https://tex.z-dn.net/?f=r%3D-k%5BH_2%5D%5BO_2%5D%5E%7B1%2F2%7D)
Explanation:
Hello!
In this case, according to the chemical reaction:
H2 + 1/2 O2 --> H2O
Since both hydrogen and oxygen are the reactants and the rate laws are written in terms of the concentration of reactants and the rate constant, we obtain:
![r=-k[H_2][O_2]^{1/2}](https://tex.z-dn.net/?f=r%3D-k%5BH_2%5D%5BO_2%5D%5E%7B1%2F2%7D)
Whereas the negative sign represents the consumption of those reactants and the power 1/2 the stoichiometric coefficient of oxygen in the reaction.
Best regards!
The answer you are looking for is <span>Vapor Pressure
</span>Vapor pressure is the pressure of vapor in contact with it's liquid. Vapor is a substance suspended into the air like a gas from a liquid. This matches your question. Therefore, Vapor pressure is the correct answer from the given choices.
I hope this helped. Have a great night!
Elements in the same group have the same amount of electrons, this affects bonding because it determines how much the element will "want" to form a covalent bond.
