The rate of chemical reaction can be increased by following ways:-
1. Adding a catalyst.
2. Increasing the temperature of system.
3. Increasing the surface area.
4. Increasing the stirring/mixing rate
5. Increasing the pressure of system (but take care as this is not always the case)

There are several factors. Concentration, size of particles, pressure, increase in temperature and the use of catalyst can increase the rate of reactions.

What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
It can be done with those substance which remains as it was before the reaction but increases the speed of the reaction.
What it will change adding a catalyst to a chemical reaction?
It will increase or decrease the speed of the chemical reaction.
What function catalyst perform in chemical reaction?
Catalysts speed up the chemical reaction.
Does glucose increases the speed of chemical reaction?
NO
What is the difference between rate of reaction and chemical equation?
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
How does a enzyme increase the speed of a reaction?
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
What effects does temperature have on chemical changes?
Generally the speed of reaction increase when the temperature is increased.
When heat is increased does the chemical reaction speed up?
The effect of heat on a chemical reaction will depend on whether the chemical reaction is exothermic (producing heat), or endothermic (requiring an input of heat). If the reaction is endothermic, then adding heat will increase the speed, but the opposite is true for an exothermic reaction.
What are two ways the speed of a chemical reaction can be increased if both of the reactants are aqueous solutions?
It can be done with those substance which remains as it was before the reaction but increases the speed of the reaction.
Will an increased temp and an increased concentration speed up a chemical reaction?
Generally, yes. Unless the product of the reaction should be ammonia for example, where a decreased temperature is needed. A catalyst from the transition metals will speed up a reaction too, for example a nickel catalyst in the process of the hydrogenation of margerine as it lowers the activation energy needed for the reaction to start. Increased pressure will also speed up the reaction, no matter what reaction is occurring.
As the temperature of a chemical reaction in the gas phase is increased the rate of the reaction increases because?
Increasing the temperature generally increases the speed with which molecules move.
What can speed up a chemical reaction by decreasing?
chemical reaction
What is chemical reaction in an enzyme?
to speed up a chemical reaction
Why does increased temperature speed up a reaction?
The motion of chemical entities increase with the temperature and the probability of collisions also increase.
What is lowered to speed up a chemical reaction?
Activation energy is lowered to speed up a chemical reaction.
How is the speed of chemical reaction related to the spontaneity of the reaction?
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
What can a chemical reaction be speeded up by?
A catalyst can speed up a chemical reaction.
