Which factor can decrease the rate of a chemical reaction? low activation energy, high pressure, low temperature, high concentration of reactants

Low temperature, can decrease the rate of a chemical reaction

Cause the temperature is related to kinetic energy, heating makes kinetic energy increase and particles move faster, will speed up the reaction that occurs

Chemical reactions involve several factors, including factors such as reactants and products and external factors such as temperature and pressure

Factors that influence the speed of reaction in product formation.

Influencing factors include:

the concentration of the reactants, the faster the reaction will be

The form of reactant molecules in the form of powder or solids affects the speed of the reaction. For the same number of masses, the smaller particle size will make the reaction run faster because the reaction involves the larger surface area of ​​the reactant

Catalysts are added to help the reaction faster

External factors that influence include:

Pressure will reduce the volume so that the reaction increases

High temperatures will speed up the reaction that occurs

If we look at the answer choices there are:

1. Low activation energy is usually due to the addition of a catalyst. The catalyst makes activation energy more lace. The activation energy itself is a minimum of energy that must be possessed to a particle so that the collision produces a reaction

2. High pressure also causes the reaction rate to be faster. The number of collisions between molecules is greater because of the distance between the molecules.

3. Low temperature

lowering the temperature makes the reaction rate run slower because the temperature is related to kinetic energy, heating makes kinetic energy increase and particles occur more often because particles move faster

4. The high concentration of reactants

the concentration of the reactants, the faster the reaction will be

So low temperature, can decrease the rate of a chemical reaction

the rate of a reaction

the rate of a reaction can be increased

Endothermic and exothermic reactions

the rate of a reaction can be increased2
