How do you calculate the rate of a reaction?

How do you calculate the rate of a reaction?

Key Points

1. Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt.
2. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.

What is the chemical reaction for h2s?

In general, hydrogen sulfide acts as a reducing agent, especially in the presence of base, which forms SH−. At high temperatures or in the presence of catalysts, sulfur dioxide reacts with hydrogen sulfide to form elemental sulfur and water.

What is the chemical formula for Sulphur?

SO₂
Sulfur dioxide/Formula

Is dihydrogen sulfide polar?

H2S is a slightly polar molecule because of its bent shaped geometrical structure and the small difference between the electronegativity of Hydrogen(2.2) and Sulfur(2.58) that results in a non zero dipole moment.

What is the chemical formula of Iron III sulfide?

Fe₂S₃
Iron(III) sulfide/Formula
Iron(3+) sulfide is a member of the class of iron(3+) sulfides that has formula Fe2S3. A black powder, it decomposes at room temperature to give iron(2+) chloride, hydrogen sulfide, and sulfur.

How is the rate of sulfide oxidation determined?

The rate of sulfide oxidation observed in batch reactors was a function of available sulfide surface area, dissolved oxygen concentration, and to a much lesser extent pH (equation 1). The dependence on surface area and dissolved oxygen indicates that the oxidation was a surface reaction with oxygen as the oxidizing agent.

How is the sulfide reaction with oxygen prepared?

The sulfide reactions with oxygen were performed in trace metal clean base, ∼15 mM NaOH. The trace metal clean base was prepared by adding NaOH to air saturated DI water and then 0.01 M MgCl 2 • 6H 2 O was added to precipitate any oxidized Fe and other trace metal contaminants.

What is the chemical formula for hydrogen sulfide?

What is the boiling point of hydrogen sulfide?

Hydrogen sulfide appears as a colorless gas having a strong odor of rotten eggs. Boiling point -60.2°C. Shipped as a liquid confined under its own vapor pressure.
