The effects of temperature on the rate of chemical reaction between calcium carbonate and hydrochlor

Show answers Print Version with answers Introduction The rate of the reaction between calcium carbonate and dilute hydrochloric acid can be judged by measuring the volume of carbon dioxide evolved with time. In this simulation you will discover the effect on the rate of reaction of altering the surface area of a solid reactant, and explain this effect in terms of kinetic particle theory.

Effect on rate of varying surface area Simulation for measuring the effect on rate of changing surface area Open Yenka file Model 1. Select 10 g of coarse calcium carbonate powder and place it in the conical flask. Reload the graph using the button on its toolbar, pour the acid into the flask and then unpause the simulation.

When 10 cm3 of gas has been collected in the syringe pause the simulation again. Record the time taken. The rate of production of gas can be calculated by dividing 10 cm3 by the time taken. Do this for your experiment, showing your working and giving units for the final answer.

You will need to change the vertical scale to a maximum of 40 cm3. This time pause the simulation when the volume reaches 40 cm3.

The effects of temperature on the rate of chemical reaction between calcium carbonate and hydrochlor

Write down the time taken. To calculate the rate of the reaction, divide 40 cm3 by the time taken. Show your working and give units for the final answer. This time pause the simulation after cm3 of gas has been produced and write down the time taken.

To calculate the rate of the reaction, divide cm3 by the time taken. List the factors, and explain the importance of keeping them constant.

Answer Volume and concentration of acid. Mass of calcium carbonate. If these are not kept constant, it will not be a fair test.

From the diagram below, it is apparent that when a cube of a substance is cut in two, two new faces are exposed, yet the mass and volume of the substance have not changed. Increasing surface area by cutting up a sample.- The Effect of Temperature on the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate Hydrochloric Acid + Calcium Carbonate à Calcium Chloride + Carbon Dioxide + Water 2HCl + CaCO3 à CaCl3 + CO2 + H2O Aim.

Search the history of over billion web pages on the Internet. The following conditions have been found suitable: a m X mm capillary column coated with a I-pm layer of phase G3; the injection port temperature is maintained at °; the detector temperature is maintained at °; the column temperature is maintained .

An improved technique of preparing massive metallic uranium by the reaction at elevated temperature between an excess of and the reaction rate of the BrF/sub 3/ with certain other solid uranium contamirnnts is sufficiently slower than the reaction rate with uranium that substantial portions of these contaminating elements will remain as.

the formation of an insoluble or volatile substance, and its elim- ination, owing to these properties, from a chemical system which otherwise would be in a condition of reversible equi- librium, may determine the entropy, and in this way the course of a reaction; obviously the same relations must prevail when the equilibrium between two.

The rate of the reaction between calcium carbonate and dilute hydrochloric acid can be judged by measuring the volume of carbon dioxide evolved with time.

In this simulation you will discover the effect on the rate of reaction of altering the surface area of a solid reactant, and explain this effect in terms of kinetic particle theory.
