Under what condition would pressure affect the reaction rate?
If the reaction occurs in the gas phase
What is present after a chemical reaction?
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
When Under what conditions is G for a reaction always positive apex?
The Gibbs free energy change (ΔG) for a reaction is always positive when the reaction is non-spontaneous under the given conditions. This typically occurs at high temperatures for exothermic reactions (where ΔH is negative and ΔS is positive) or when the entropy change (ΔS) is negative while ΔH is positive. In such cases, the term TΔS is not large enough to overcome the positive ΔH, resulting in a positive ΔG.
monobromination of acetanilide occurs,while tribromination of aniline would occur under the same conditions?
Write a detailed set of equations for the acetylation reaction, and in particular show clearly that the reaction can be regarded as a nucleophilic substitution, in which the attacking nucleophile is aniline (attacking acetic anhydride).
What are the conditions needed for hydrogen and iodine to react?
For hydrogen and iodine to react, they need to be in the gaseous state, typically at elevated temperatures to overcome the activation energy barrier. The reaction is initiated by heat, light, or a catalyst, producing hydrogen iodide (HI). Additionally, the reaction occurs more readily under conditions where the concentrations of the reactants are relatively high.
Under what condition would pressure affect the reaction rate?
If the reaction occurs in the gas phase
What does the subscript r stand for in chemistry qr?
The subscript r in chemistry typically refers to a rate constant in a chemical reaction. It represents the rate at which a reaction occurs under specific conditions.
Under what conditions is G for a reaction always positive?
When H is positive and S is negative
What information does a chemical equation not provide?
A chemical equation does not provide information about the speed of the reaction, the physical state of the reactants and products, or the mechanism by which the reaction occurs. Additionally, it does not give information about the conditions under which the reaction is taking place, such as temperature, pressure, or catalysts.
What is the reaction of argon?
Argon is chemically inert and does not have any reaction under normal conditions.
What type of reaction occurs to fossils under pressure in the sediment?
Chimical
What are the limitations of the chemical equation?
Chemical equations do not provide information about the speed of a reaction, the conditions under which a reaction occurs, or the purity of the reactants. They also do not account for side reactions or variations in reaction pathways. Additionally, chemical equations do not indicate the physical state of reactants and products or the equilibrium state of a reaction.
What was the outcome of the reaction?
To provide a specific outcome of a reaction, please specify the particular chemical reaction or context you are referring to. Outcomes can vary widely based on the reactants involved and the conditions under which the reaction occurs. Typically, a reaction can result in the formation of new products, changes in energy, or shifts in equilibrium, among other outcomes.
When does an equilibrium occur?
An equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time. Equilibrium can only be reached in a closed system under certain conditions, such as constant temperature and pressure.
Why look for black precipitation in the butt instead of on the surface of an H2S test?
The black precipitate usually sink to the bottom which the reaction took place in. The reaction takes place at the bottom because it only occurs under anaerobic conditions, and it does not sink to the bottom as it only occurs at the bottom, not around oxygen at the top of the tube.
What is the chemical reaction of Bromine and Plutonium?
When bromine reacts with plutonium, it forms plutonium bromide. The chemical equation for the reaction is: 2Pu + 3Br2 → 2PuBr3. This reaction typically occurs under controlled laboratory conditions due to the high radioactivity of plutonium.
What is present after a chemical reaction?
That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
