Why the reaction stops quickly when sulphuric acid is added to marble chips?
When sulfuric acid is added to marble chips, a chemical reaction takes place in which the acid reacts with the calcium carbonate in the marble to produce carbon dioxide gas. This gas forms bubbles which can create a layer around the marble chips, limiting further contact with the acid and slowing down the reaction. Once the layer of gas forms, the reaction rate decreases, resulting in the rapid reaction coming to a halt.
How can you speed up the chemical reaction between lemon juice and marble?
You can speed up the chemical reaction between lemon juice (acid) and marble (calcium carbonate) by increasing the temperature, crushing the marble to increase surface area, or using a catalyst like citric acid to enhance the reaction rate.
Why are marble chips not soluble in water?
Because Marble chips, Calcium carbonate, (CaCO3), require an acidic pH (less than 7) in order to dissolve at a useful rate*. The lower the pH, the faster it reacts. At a pH of ~8 or higher, it loses almost all of its aqueous solubility.* Actually marble chips are slightly soluble in water. This is why they make such great stalactites and stalagmites. However, for most practical purposes, they are insoluble in water because they dissolve at a very slow rate, slow enough to be impractical for almost any useful purpose.Related Information:Decomposition occurs at various stages and many products and byproducts are formed, depending upon the pressure, temperature, and pH, all of which tend to vary at given stages of reaction. It decomposes, more than dissolves. Products can include:CaO,Ca(HCO3)2,H2CO3,Ca(OH)2,Ca+2,CO3-2,HCO3-,H+,CO3-2CO2H2O,OH-,
What does the rate law use to determine the rate of a reaction?
The rate law uses the concentrations of reactants to determine the rate of a reaction. By experimentally determining the relationship between the rate of reaction and the concentrations of reactants, we can derive the rate law equation for that specific reaction.
What is the relationship between the rate law and zero order in a chemical reaction?
In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants. The rate law for a zero-order reaction is rate k, where k is the rate constant. This means that the rate of the reaction is constant and does not change with the concentration of the reactants.

What factor is likely to change the rate of reaction between marble and acid rain?

How does tempreture affect the reaction rate?
Tempreture effects the reaction rate because if you put marble chips/whatever in higher acid and less water such as; 15cm of acid and 10cm of the results get slower and slower throughout the time but at the same time it increases. hope this helped you guys:)
How long does it take for a lump of marble to produce 20ml of gas?
The time it takes for a lump of marble to produce 20ml of gas can vary depending on factors such as the size of the marble, temperature, and the reaction taking place. In a chemical reaction like the reaction between marble (calcium carbonate) and acid (such as hydrochloric acid), gas is produced. The rate of gas production can be affected by the concentration of the acid, temperature, and the surface area of the marble.
How can you speed up the chemical reaction between lemon juice and marble?
You can speed up the chemical reaction between lemon juice (acid) and marble (calcium carbonate) by increasing the temperature, crushing the marble to increase surface area, or using a catalyst like citric acid to enhance the reaction rate.
Why you are adding marble chips during heating?
Marble chips are added during heating so that the solution or substance can boil evenly. Evenly boiling the solution will cause it not to have heating spots, which can cause an eruption of bubbles. Heating spots are caused when the heat being applied is only getting to the liquid at the bottom of the flask, causing the liquid down there to evaporate more quickly than the upper liquid. The liquid evaporating causes bubbles to shoot through the solution vigorously, disrupting the system. To avoid these heating spots, we add marble chips or boiling chips to induce a nice, even boil.
Why you use the porcelain chips as the catalyst for the dehydration of ethanol?
Porcelain chips are used as a catalyst for the dehydration of ethanol because the rough surface of the chips provides a large surface area for the reaction to occur, allowing for more contact between the reactants and catalyst. This helps to enhance the rate of the dehydration reaction and improve the overall efficiency of the process.

What is the relationship between concentration and reaction rate?
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.
What is the relationship between the rate law and zero order in a chemical reaction?
In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants. The rate law for a zero-order reaction is rate k, where k is the rate constant. This means that the rate of the reaction is constant and does not change with the concentration of the reactants.
What does the rate of law use to determine the rate of a reaction?
The rate of a reaction is calculated using the concentrations of reactants.
