How does the size of marble chips affect the rate of reaction?

How does the size of marble chips affect the rate of reaction?

For a given quantity, if the chips are larger then the surface area is lesson. So reaction with the larger chips happens more slowly.

Why does marble powder reacts faster than marble chips?

Explanation of effect: There are more reactant particles immediately available to react because the surface area of the powder is greater than that of the chip. There is greater exposure of the marble particles so there are more available for the acid particles / hydrogen ions / H+ ions to collide with.

How can the rate of reaction be increased in an experiment?

There are 4 methods by which you can increase the rate of a reaction:

1. Increase the concentration of a reactant.
2. Increase the temperature of the reactants.
3. Increase the surface area of a reactant.
4. Add a catalyst to the reaction.

Will lumps of CaCO3 reacts faster than powdered CaCO3?

The large lump of CaCO3 has a small surface area relative to the same mass of powdered CaCO3. As a result, there can be more successful collisions per unit time and the reaction of powdered CaCO3 is faster. Increasing the surface area of the reactants increases the rate of the reaction.

Why do marble chips fizz when added to acid?

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. The rate of this reaction can be changed by changing the size of the marble chips.

Why do the eight small marble chips react faster than the large marble chip answer?

The eight small marble chips have a smaller surface area, so less frequent collisions. The eight small marble chips have a smaller surface area, so more frequent collisions.

How do you determine the rate of a reaction?

Measuring Reaction Rates

1. Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt.
2. The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.

What is marble chip?

marble chips (calcium carbonate) are added to hydrochloric acid. the volume of carbon dioxide produced is measured over the same period of time. the marble chips are completely used up, in every case.

What 4 things affect the rate of reaction?

The factors that affect reaction rates are:

• surface area of a solid reactant.
• concentration or pressure of a reactant.
• temperature.
• nature of the reactants.
• presence/absence of a catalyst.

What are the 5 factors that affect the rate of reaction?

Five factors typically affecting the rates of chemical reactions will be explored in this section: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the …

Why does particle size affect reaction rate?

Surface Area / Particle Size Breaking the reactant into smaller pieces increases the surface and more particles are exposed to the reaction mixture. This results in an increased frequency of collisions and therefore a faster rate of reaction.

Does volume of acid affect rate of reaction?

Under higher pressure or at a higher concentration, gas molecules collide more frequently and react at a faster rate. Conversely, increasing the volume of a gas decreases pressure which in turn decreases the collision frequency and thus reduces the reaction rate.

How are rates of reaction between marble chips and hydrochloric acid?

My results show a steady in crease in the rates of reaction between Hydrochloric acid and Marble chips. This happens because the weaker the concentration of hydrochloric acid the fewer particles there are to collide with the Marble chips. In my prediction I said that I thought the weaker the concentration the longer the rate of reaction would be.

What is the mass of a marble chip?

The mass of marble chips will be 0. 5 Grams. I will be using medium sized marble chips, dependant on the mass. I will be doing the experiment at room temperature. Control Of Variables Variable How Controlled Units Concentration (HcL) 2 M, 1.

Why does the rate of reaction between aim chips increase?

Aim. Chips ( Calcium Carbonate) and Hydrochloric acid per minute. Hypothesis. The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by increasing the surface area we are also increasing the rate of collisions between the particles.

Why is acid rain bad for marble statues?

The purpose of this experiment is to discover the reaction rate in which acid rain weathers marble statues, or in our case, marble chips. Marble is especially sensitive to the degrading by acidic chemicals, also to weathering. Acid rain is one of the top degradation agents for marble artifacts around the world.
