What is the rate constant for formation of ethylene oxide?

The rate constant for the formation of ethylene oxide can vary depending on the reaction conditions, such as temperature, pressure, and catalyst used. It is typically determined experimentally through kinetic studies for the specific reaction being studied.


What is the conditional formation constant for the reaction between EDTA and Ca2 plus at pH equals 10?

The conditional constant= 1.8*1010


How does threshold frequency relate to work function?

Threshold frequency is the minimum frequency of light required to eject an electron from a metal surface, while work function is the minimum energy required to remove an electron from the metal. The threshold frequency is directly related to the work function by the equation E = hf, where E is the energy required, h is Planck's constant, and f is the frequency of the incident light.


How to Calculate the work function?

work function = planck's constant x threshold frequency w=h(ft) it also equals the energy(eV) Planck's constant(h) = 6.626 x 10-34


What is the formation constant for dithiosulfato argentate?

The formation constant for dithiosulfato argentate, [Ag(S2O3)2]3-, is approximately 1.04 x 10^21. This complex is formed between silver ions and dithiosulfate ligands, resulting in a stable coordination compound.


What year earths gravitational constant invented?

The earth's gravitational constant was created about 4.5 billion years ago, with the formation of the planet within the Solar System.


What is chronic apical pulmonary fibrosis?

Chronic apical pulmonary fibrosis refers to scarring or fibrosis that occurs in the upper parts of the lungs, usually concentrated at the apices. This condition may be associated with conditions like tuberculosis, asbestos exposure, or certain autoimmune diseases. Symptoms can include cough, shortness of breath, and chest pain.


How is the threshold frequency related to work function?

The threshold frequency is the minimum frequency of light required to eject electrons from a metal surface (photoelectric effect). The work function is the minimum energy needed to remove an electron from the metal surface. The threshold frequency is directly related to the work function through the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency.


What is the Kc value for FeSCN?

The equilibrium constant Kc for the formation of FeSCN2+ is around 685 M^-1.


How can the magnitude of an equilibrium constant indicate the extent of a reaction?

The magnitude of the equilibrium constant indicates the position of equilibrium for a reaction. A larger equilibrium constant suggests that the reaction favors the formation of products, while a smaller equilibrium constant indicates that the reaction favors the formation of reactants. The magnitude can therefore give insight into how much product is formed at equilibrium compared to reactants.


What is an equillibrium constant?

The equilibrium constant, denoted as K, is a measure of the extent of a chemical reaction at equilibrium. It is the ratio of the concentrations of products to reactants at equilibrium, each raised to the power of their respective stoichiometric coefficients. A large value of K indicates the reaction favors the formation of products, while a small value indicates the reaction favors the formation of reactants.


What is the schwarzschild radius of earth?

The schwarzschild radius of the Earth is about 8.7 x 10 to the negative 3m. The schwarzschild radius is the radis of a sphere that is around a non-rotating blackhole. You find the Rs, or radis, by multiplying the gravitational constant(G), the mass(M), and two. You divide this by the speed of light(c) squared.
