How does a factor affect the rate of a reaction between Calcium Carbonate and acid.?
971455
there are various factors which affects rate of reaction. like temperature,pressure and concentration of the reactants involved. and they all have different effects

Carbonic acid is the one that usually affects limestone bedrock.\n\nCarbonic acid forms when decaying matter interacts with filtering water.\n\nAs it moves down through cracks in the bedrock, it slowly dissolves the limestone. Over time the cracks grow & enlarge eventually making miles of underground caves & caverns.\n\nThe type of topography associated w/ dissolution of limestone bedrock is called Karst Topography.\n\nKarst simply refers to that which you can see above ground like sinkholes (collapsed caverns/caves) & Karst lakes (sinkholes filled w/ water).

Collision theory predicts that rate of reaction will increase with increasing reactant concentration, because the higher the concentration the greater the number of particles and hence the greater number of collisions. If there are MORE collisions then the number (NOT the proportion) of successful collisions will also increase, therefore rate will increase.\nSo if you're plotting reaction rate vs acid concentration your graph will have a positive gradient and each incremental increase in concentration will have the same effect on the rate of reaction.

This is very simple\n\nCa+H2O -> Ca(OH)2 + H2\n\nThe reactant has\n1 atom of Ca\n1 atom of H\n2 atoms of O\n\nThe product has\n1 atom of Ca, ok\n2 atoms of H\n2 atoms of O\n\nJust put a coefficient of 2 in the water (H2O)\n\nSo the chem. eqn becomes\n\nCa+2 H2O -> Ca(OH)2 + H2\n\nThat's it.\nThe equation is already balance

time= 2.303/(rate constant) log( initial conc / final conc)\n\nthis is for a first order reaction...

The greater the Kb value is, the stronger the base.  Just think about what Kb means.  On the left side of the equilibrium is the base, on the right side is the conjugate acid, meaning the base has reacted.  The stronger the base, the more it will react, the more the reaction will proceed to the right, the greater Kb will be.\n\nSo.....\n\nC > E > B > A > D

1.  Heat speeds up a reaction by increasing vibrations and energy of the reactants.\n\n2.  Concentration speeds us a reaction by making more reactants available in a unit volume.\n\n3.  Catylists speed up a reaction (without being used up) by allowing reactants to come into closer proximity.\n\n4.  Increased surface area (by grinding, etc.) speeds up reactions by making more reactants exposed to reaction.

When you boiled the water, you evaporated some of it. This increases the salt concentration in the water which alters the ph. Since it went toward the alkaline side, it probably increased the calcium salts in the water.

It depends on the rock composition and it depends on the acid strength.  Calcite will bubble with Hydro-chloric acid.

Yes it has something to do with acids.\n\nLimestone is CaCO3 deposits. If you look at the acid-base reaction between an acid and CaCO3 you can see that the carbonate ion favors being protonated and because of the fact that it's protonated state is very unstable it readily becomes water and CO2 gas. \n\n2 H+ + CO3 2- ---> H2CO3 ---> H2O + CO2\n\nThese two products of the reaction are very healthy for environments. However, since this reaction doesn't occur in areas of mostly granite, these bi-products aren't produced leading to the acid having a more detrimental affect on the surrounding environment.

What you have as your reactant is really just expressing a complicated equilibrium for the sodium salt of a carboxylic acid.  You have calcium ion in your products, but not your reactants, which is a no-no.  Having said that, it looks like you're replacing the sodium ion with calcium ion as the cation associated with carboxylate anion.  Separating all of the reactants from one another won't be easy, but you could try adding calcium hydroxide.  That should precipitate sodium and calcium carbonate.

I forget my organic chem but\n\nammonia, calcium carbonate - a base is used to neutralize an acid - a base donates electrons and an acid collects them (i think, or vs/vs) \n\nboth can be used to separate other chemicals, or remove chemicals from mixtures\n\nAcids are often used as a catalyst to start a reaction like when producing explosives - and can be very dangerous\n\ncommon ex - bleach(acid) mixied with ammonia(base) produce a poisonous gas and heat which can actually cause sever damage to lungs

2NO+O2--->2NO2\n\nCaO+H2O--->Ca(OH)2\n\nCaCO3--->CaO+CO2

the only way to determine the rate of a reaction is to do the experiment yourself.\n\nUse starch as the indicator and plenty of acid.

Calcium Carbonate (CaCO3) is insoluble, therefore it is the precipitate --> makes the solution cloudy.  The H2O is just plain old water. I believe the equation to which you are referring is H2CO3 + Ca(OH)2 --> CaCO3 +H2O, however, but no big deal.

Given that a certain type of molecule is small enough to permeate through the cell membrane, the most important factor influencing the rate of diffusion is the concentration gradient.  This is simply the difference in concentration levels of the substance between the outside and the inside of the cell.  The larger the difference in concentrations, the greater the rate of diffusion.
