Reaction rate is determined partly the chemical activity of the reacting components. In general, if you lower concentation (dilution) you lower the activity.
The Reaction Rate
This is called reaction rate.
The reaction between hydrochloric acid (HCl) and magnesium (Mg) is a good example. By increasing the concentration of HCl, the rate of reaction will increase, producing hydrogen gas at a faster rate. This can be visually observed by monitoring the rate at which bubbles of hydrogen gas are released.
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
Acid is diluted in titration to achieve accurate and precise results. Diluting the acid helps control the rate of the reaction and ensures that the endpoint is reached at the correct volume of titrant, making the titration more reliable and reproducible.

No, the reaction between hydrochloric acid and calcium carbonate is not a first order reaction. It is a decomposition reaction where the rate of reaction will not be constant as the concentration of the reactants change over time.
Heat can change the rate of reaction

If the sulfuric acid is left out of the reaction, the acetylsalicylic acid synthesis may proceed at a slower rate or not to completion. The presence of sulfuric acid helps catalyze the reaction and improves the yield of acetylsalicylic acid. It also helps in the dehydration of acetic acid formed during the reaction.
Yes, the rate constant can change with concentration in a chemical reaction.
The Reaction Rate
The rate of reaction between HCl and marble chips is dependent on factors such as the concentration of the acid, the surface area of the marble chips, and the temperature of the reaction. As the concentration of the acid increases, the rate of reaction also increases due to more collisions between the acid molecules and the marble chips. Similarly, a higher temperature increases the kinetic energy of the particles, leading to more collisions and a faster reaction rate. The surface area of the marble chips affects the rate of reaction by providing more sites for acid molecules to react with, which speeds up the reaction.
Water for one. If a reaction is diluted, the components of the reaction are less likely to contact one another. This will mean that they will be also less likely to continue a reaction.
The concentration of acid is very important when you are thinking about the rate of reaction. The more concentrated the acid is, the more particles there are to react with the other substance. This results in a faster and more vigorous reaction.
Yes, pounding chalk into powder will increase the rate of reaction with hydrochloric acid. This is because crushing the chalk into a powder increases its surface area, allowing more of it to come into contact with the hydrochloric acid and react.
