Distinguish between the differential rate law and the integrated ratelaw. Which of these is often called just the "rate law"? What is k in a rate law, and what are orders in a rate law? Explain.

Answers

Answer 1

Differential rate law describes the rate of reaction as a function of reactant concentrations, changing with time. Integrated rate law describes the change in reactant concentration over time and is often used to find the half-life of a reaction.

The term "rate law" is commonly used to refer to the integrated rate law. K in a rate law is the rate constant, a value specific to each reaction that determines the rate of reaction. Orders in a rate law describe the dependency of the reaction rate on the concentration of each reactant, with each reactant having its own order. The overall reaction order is the sum of the individual orders, which can be determined through experiments.

which of the following would change the vapor pressure of a sample of water in a closed container? 1. decreasing the size of the container 2. lower the container temperature 3. removing water from the container

Answers

All of the above options would change the vapor pressure of a sample of water in a closed container.

Decreasing the size of the container would increase the vapor pressure because the number of water molecules in the container would be more concentrated.Lowering the container temperature would decrease the vapor pressure because the water molecules would have less kinetic energy and would therefore be less likely to escape as a gas.Removing water from the container would decrease the vapor pressure because there would be fewer water molecules in the container.

Vapor pressure is a measure of the tendency of a substance to turn into a gas at a given temperature. It is related to the kinetic energy of the molecules of the substance, with more energetic molecules having a higher vapor pressure. In a closed container, the vapor pressure of a liquid will be determined by the temperature and the number of molecules present.

It's also worth noting that the vapor pressure of a liquid is also related to its boiling point. The boiling point is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure. As the vapor pressure of liquid increases, its boiling point increases, and as the vapor pressure decreases, its boiling point decreases.

Concentration of A to decrease to 1/e (37%) of its initial value is approximately 2.1 seconds. The rate of a second-order reaction is given by the equation: rate = k[A]^2 .

Where k is the rate constant and [A] is the concentration of the reactant. Given that the rate constant is k = and the initial concentration of A is [A]0 = , we can use the above equation to determine the rate of the reaction.

rate = k[A]^2 = ()( )^2

To find out how long it takes for the concentration of A to decrease to 1/e (37%) of its initial value, we can use the following equation:

[A] = [A]0e^(-kt) ,

Answers

The exothermic dissolution of mg(oh)2(s)will increase the solubility of mg(oh)2 in an aqueous solution increasing the pH.

The solubility of a substance in water is affected by its solubility product constant (Ksp) and the pH of the solution. Ksp is a measure of the maximum concentration of a substance that can be dissolved in water at a given temperature and pressure. In this case, the Ksp of Mg(OH)2 is 1.8 x 10-11.

Increasing the pH of the solution will increase the solubility of Mg(OH)2 because it will shift the equilibrium of the dissolution reaction in favor of the products. This is because the dissolution reaction is exothermic, meaning that heat is released when the Mg(OH)2 dissolves. This heat release causes the equilibrium to shift towards the product side.

On the other hand, decreasing the pH, adding NH3, or adding Mg(NO3)2 will not affect the solubility of Mg(OH)2 in the solution. Hence options a, c, and d are not correct.

Thus, in order to find the number of moles present in a substance, the mass of the substance must be known and the molar mass is calculated appropriately.

Since the molar mass of substances is determined from the sum of molar masses of atoms of elements present in the chemical formula of the substance, the molar mass is theoretical.

What is password-protection?

Password protection is an access control technique that helps keep important data safe from hackers by ensuring it can only be accessed with the right credentials. Password protection is one of the most common data security tools available to users—but they are easily bypassed if not created with hackers in mind.

Password protection is a security process that protects your computer from unauthorized access via authentication and verification processing. In simple words, your online information is protected using a unique password – only an authorized user with the correct password can view the content.

Passwords provide the first line of defense against unauthorized access to your computer and personal information. The stronger your password, the more protected your computer will be from hackers and malicious software. You should maintain strong passwords for all accounts on your computer.
