The characteristics and rate of the decomposition process depend on which factors

The rate of all reactions is mainly influenced by four factors: concentration, temperature, pressure, and catalyst. In addition, factors such as galvanic cell formation, light, surface area of solid matter also affect the rate. The decomposition reaction has no peculiarities in terms of the factors influencing the rate.

It is known from the decomposition condition test data of the calciner that it affects carbonates.

The decomposition of the branches is as follows. As the temperature increases, the decomposition rate accelerates and the decomposition time shortens. Carbon dioxide.

Concentration 32The lower the concentration, the more favorable it is for carbonate decomposition. The fineness of the raw meal is fine, and the decomposition rate is faster. The contact area between suspension dispersion and airflow in the dispersed state of raw meal increases, and the decomposition rate increases rapidly.

The quality of the limestone structure is dense and coarsely crystalline, and the decomposition rate is slow. Clay activity in raw meal can be combined with calcium carbonate at 800°C.

or calcium oxide reacts to accelerate the decomposition of calcium carbonate. Temperature is a sign of the kinetic energy of a molecule, and when we increase the temperature, the energy of the molecule increases. The increase in the energy of the molecules can be manifested as an increase in the speed of the molecules' movements.

When molecules moving at high speed collide, then their effective collision increases, and the chance of a real chemical reaction occurs, which ultimately leads to a chemical reaction rate.

Enlarge. The change in pressure is to reduce the volume in chemistry, and when we increase the pressure of a container containing a chemical reaction containing gas, it is also a decrease in volume. When we reduce the volume, it causes the concentration of gas-related substances to increase, and if the concentration increases, it will cause an effective collision per unit volume.

The increase in the number of times in the chemical reaction further increases the increase in the rate of chemical reactions. If we increase the concentration, that is, the total number of molecules per unit volume increases, due to the increase of the total number of molecules per unit volume, the number of collisions per unit volume increases, that is, the effective number of collisions increases, so the chemical reaction rate increases, that is, increasing the concentration can increase the chemical reaction rate.

The size of the solid particles, when other conditions are the same, the smaller the solid particles, the larger the surface area of the reactants, and the faster the reaction rate of the chemical posture source. The smaller the solid particles, the smaller the surface area of the solid reactants and the lower the rate of chemical reactions. The concentration of reactants, when other conditions are the same, increase the concentration of reactants, and the chemical reaction rate accelerates; The concentration of reactants is reduced, and the reaction rate is reduced. The temperature of the reactants.

When other conditions are the same, the temperature of the reactants is increased, and the chemical reaction rate is fast. Reducing the temperature of the reactants reduces the reaction rate. Catalysts, all other things being equal, use catalysts to change the rate of chemical reactions. The pressure of the gaseous reactants, when other conditions are the same, the pressure of the gaseous reactants increases, and the chemical reaction rate is accelerated. The pressure of the gaseous reactants, the chemical reaction rate is fast.
