What is a change that affects chemical reaction rate?
Factors affecting the reaction rate:- Concentrations of the reactants- Temperature- Pressure- Sirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
Is a substance that increases the rate of a chemical reaction.?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
Heat of reaction for a chemical reaction symbol?
The symbol used to represent the heat of reaction in a chemical equation is ΔH. It indicates the enthalpy change of the reaction, which is the heat exchanged during a chemical reaction at constant pressure.
The rate of chemical reactions depend on what four things?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
What kind reaction is used for electroplating?
Electrodeposition/electrolysis are the chemical reactions involved in electroplating.
What is a high pressure reactor?
High pressure reactor is a chemical reaction vessel which can conduct a reaction under pressure. The pressure can be caused by the reaction itself or created by an external source. Reactor can be used for sample modification with hydrogen, carbon dioxide, acetylene etc.
What is meant by equation?
a proper chemical equation is a representation of a chemical reaction by the means of symbols and formulae that displays the reactants,catalysts,external forces like sound,pressure,heat etc. and products.
What is a change that affects chemical reaction rate?
Factors affecting the reaction rate:- Concentrations of the reactants- Temperature- Pressure- Sirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
When does heat equal enthalpy in a chemical reaction?
Heat equals enthalpy in a chemical reaction when the reaction is carried out at constant pressure.
What is meant by proper equation?
a proper chemical equation is a representation of a chemical reaction by the means of symbols and formulae that displays the reactants,catalysts,external forces like sound,pressure,heat etc. and products.
When does the change in enthalpy equal heat in a chemical reaction?
The change in enthalpy equals the heat in a chemical reaction when the reaction occurs at constant pressure.
When is q equal to delta h in a chemical reaction?
Q is equal to delta H in a chemical reaction when the reaction is at constant pressure and temperature.
Is a substance that increases the rate of a chemical reaction.?
Factors affecting the reaction rate: - Concentrations of the reactants- Temperature- Pressure- Stirring- Catalysts- Granulometry (and the surface area) of the reactants- Reaction order- Type of the reaction- The solvent used- External factors as irradiationetc.
What is the difference between the present value of an investment and its cost?
pressure is dependent on temperature pressure is a mere important factor that affect chemical reaction temperature acts on chemical reaction faster than pressure
When does q equal delta h in a chemical reaction?
Q equals delta H in a chemical reaction when the reaction is at constant pressure and the temperature remains constant.
How does pressure speed up a chemical reaction?
Increasing pressure can speed up a chemical reaction by bringing reactant particles into closer contact more frequently, leading to more successful collisions. This increased pressure can also alter the equilibrium of the reaction, favoring the formation of products. Additionally, higher pressure can increase the energy of the collisions between reactant particles, making them more likely to overcome the activation energy barrier for the reaction to occur.
What are essentials of a chemical reaction?
Essentials are the reactants, temperature, pressure, concentrations, rate of reaction, yield of reaction etc.
