Adding a catalyst to the process will make the chemical reaction go faster.

Also, the temperation, concentration, state of matter and pressure will affect the rate of the chemical reaction.

The rate of reaction is affected by temperature,concentration,particle size, and the use of a catalyst.

1. Temperature (An increase in temp causes there to be an increase in kinetic energy. This results in an increase in collision frequency and therefore, an increase in rate of reaction.)

2. Concentration (An increase in concentration increases the probability of collisions. This causes there to be an increase in rate of reaction as well.)

3. Particle Size (A decrease in particle size results increases the surface area. This increases the #of collisions which also increases the rate of reaction.)

4. Use of a Catalyst (A catalyst increases the chance of particles meeting and lowers the activation energy. This results in an increase in the rate of reaction.)

Which of these factors will not affect reaction rates?

The proper term for the phenomenon of reaction rates is known as chemical kinetics. Generally for any chemical reaction factors such as temperature, concentration, pressure, physical state, presence of a catalyst, and the reaction rate order. Reaction rate order is specific for each chemical reaction. So to sum it all up, if you influence the environment in a manner that does not change one of these listed variables, then it will not likely do anything to a reaction rate. But to be honest, I can't think of a single thing you could do to a reaction that wouldn't influence one or more of these parameters.


Is souring milk an example of a chemical change?

Yes it is a chemical reaction between the calcium and the oxygen [i may be wrong their] but the rate of reaction is very slow.


Which factors must be equal in a reversible chemical reaction at equilibrium?

the rate of te forward reaction and the rate of the reverse reaction


What change will most likely increase the rate of a chemical reaction?

Factors which can increase the rate of a chemical reaction:- temperature- pressure- concentration of reactants- stirring- if solids are involved the dimension of particles is important- the type of reaction- the order of reaction- presence of catalysts- influence of external factorsetc.


What effect does the concentration of reactants have on the the rate of a reaction?

The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.

Is this how you spell calysis?

The process is spelled catalysis (change in reaction rate).The substance that makes a chemical reaction change is a catalyst.
