Kinetic and Stoichiometry

Question 1

Average reaction velocity equation

Answer 1

Δ[Substance]/Δt

Question 1

What is the relationship between the sign of velocity and the reaction?

Answer 1

Positive reaction velocity = Speed of formation of products
Negative reaction velocity = Speed of consumption of reactants

Question 2

What is the relationship between average reaction velocity and the velocity of reaction of particular elements within it?

Answer 2

Vr = Vs/Substance Coefficient

Vr * Substance Coefficient = Vs

Question 3

What is the product of solubility constant?

Answer 3

Ksp = [A]^a * [B]^b

For the final concentrations of the ions in solution

Question 4

What is the difference between distilação and titulação?

Answer 4

Distilação: Utilizar diferentes pontos de ebulição de substâncias para separá-las ao manter uma líquida e a outra gasosa

Titulação: Identificar uma substâcia ao utilizar uma uma substância de pH conhecido e um indicador ácido-base para medir mudanças no pH ao misturá-las.

Question 5

What is order of reaction?

Answer 5

Order of reaction of a reagent = degree to which changing the concentration of a reactant changes the rate of reaction, it is the a in the [A]^a rate reaction, or the power that the concentration of the reactant is raised to in the rate reaction and equilibrium equation. The order of the whole reaction is the summ of the order of the reactants

Question 6

What are the non-hydrogen intermolecular forces?

Answer 6

1. Ion-dipole
2. Dipole-Dipole
3. Dipole - Induced Dipole
4. Ion - Induced Dipole
5. London Dispersion (Induced-Induced)

Question 7

What is Intermolecular Hydrogen bond?

Answer 7

Hydrogen bound to a highly electronegative atom becomes positively charged and attracts another highly electronegative atom, though they are not covalently or ionically bonded.
