This is an incomplete question, here is a complete question and an image is attached below.
The following diagrams represent mixtures of NO(g) and O₂(g). These two substances react as follows:
It has been determined experimentally that the rate is second order in NO and first order in O₂.
Based on this fact, which of the following mixtures will have the fastest initial rate?
The mixture (1). The mixture (2). The mixture (3).
Answer : The mixture 1 has the fastest initial rate.
Explanation :
The given chemical reaction is:
The rate law expression is:
Now we have to determine the number of molecules of
In mixture 1 : There are 5 and 4
molecules.
In mixture 2 : There are 7 and 2
molecules.
In mixture 3 : There are 3 and 5
molecules.
Now we have to determine the rate law expression for mixture 1, 2 and 3.
The rate law expression for mixture 1 is:
The rate law expression for mixture 2 is:
The rate law expression for mixture 3 is:
Hence, the mixture 1 has the fastest initial rate.
Answer:
The answer is
<h2>8.4 mL</h2>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 88.2 g
density = 10.5 g/cm³
The volume is
We have the final answer as
<h3>8.4 mL</h3>Hope this helps you
