Answer:
molecularity of the rate-determining step
Explanation:
The rate determining step of a sequence of reactions is the slowest step in the sequence of non-elementary reactions.
The molecularity of the slowest step in the reaction mechanism gives us the rate law of reaction.
It is for this cause that the slowest step in the reaction sequence is called ''rate determining step'' since it determines the rate law of reaction.
Answer: At temperature of 269 K the gas would occupy 1.33 L at 217 kPa
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 147 kPa
= final pressure of gas = 217 kPa
= initial volume of gas = 1.8 L
= final volume of gas = 1.33 L
= initial temperature of gas =
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Thus at 269 K temperature the gas would occupy 1.33 L at 217 kPa
We see that in the left-hand side of the equation, the side of the reactants, that we have 2 moles of Na and bromine is in it's diatomic form.
Therefore, we have 2 moles of each of these elements. When we combine the sodium bromide molecule in the products, we are going to want to keep these molar amounts the same. So we are going to need to put a 2 in front of the sodium bromide in order to correctly balance this equation.
So the coefficient for sodium bromide (NaBr) in this equation is 2.
