Answer:
Explanation:
Hi there,
To get started, let's first observe our rate law:
![R=k[A]^2[B]^2](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E2%5BB%5D%5E2)
we typically use square brackets [x] for chemistry kinetics, because they specifically tell us we are dealing with <em>concentrations</em>.
This rate law is in fourth-order, because the concentrations powers add up to 4. We are not told the unit of time for this prompt (unless you know it), so I just assumed the time unit to be "time."
To calculate the reaction rate, we simply plug in the concentration of A and B into the rate law. k is the <em>rate constant</em> and stays the same for an individual reaction.
![R=(0.1 \ M^{-3}*time^{-1})[1 \ M]^2[2 \ M]^2=0.4 \ M/time](https://tex.z-dn.net/?f=R%3D%280.1%20%5C%20M%5E%7B-3%7D%2Atime%5E%7B-1%7D%29%5B1%20%5C%20M%5D%5E2%5B2%20%5C%20M%5D%5E2%3D0.4%20%5C%20M%2Ftime)
Thus, the rate of reaction with those concentrations is 0.4 M/time.
Notice, the rate constant does in fact have units of it own. The unit for k can be calculated by knowing that:
- Rate (R) must end up with units of concentration (M) per time.
- The concentrations raised to a power can be used to help solve for the units of k.

Answer:
AlF3
Explanation:
Aluminum fluoride is an inorganic compound of chemical formula AlF3. Such a compound originates from the treatment of aluminum hydroxide particles with hydrogen fluoride, which react and give rise to aluminum fluoride. This is a very important solid and crystalline element during the production of other compounds that use aluminum oxides because it has the ability to lower the melting point.
The molarity of the resulting solution is 0.65 M.
<h3>Which molarity is it?</h3>
- To be able to comprehend what we mean by the molarity of a solution, we must first go back in time. We are aware that molarity refers to the concentration of the component in the solution. In this situation, it's important to be aware that the molarity can only be represented in terms of moles per litre.
- The number of moles of the gas must now be determined, and this can only be done by applying the ideal gas equation, which is what we will be able to accomplish in this issue.
PV = nRT
Pressure is P.
Volume is V.
The number of moles is n.
Gas constant R
Temperature is T
n = PV/RT
n = 0.97 * 12.7/0.082 * 306
n = 12.3/25.1
N=0.49 moles.
Number of Mole/Volume Equals Molarity of the Solution
0.49 moles/0.750 liters
= 0.65 M
