What happens when CaCO3 is heated in closed vessel and open vessel?

CaCO3 will decompose ( dissociate) to form CaO and CO2 gas.

How many phases exist in case of mixture of CaCO3 and CaO?

Thus is an one component system. The composition of each of the three phases can be expressed in terms of at least any two of the independent variable constituents, CaCO3, CaO and CO2.

What are the number of phases when calcium carbonate is heated in a closed vessel?

The minimum number of components for the system you described is 2 (CaO and CO2) if we assume the conditions are such that no other substances such as CO are being formed.

Is CaO solid?

Calcium oxide, CaO, also known as lime or more specifically quicklime, is a white or grayish white solid produced in large quantities by roasting calcium carbonate so as to drive off carbon dioxide.

What are the limitations of phase rule?

The limitations of phase rule are as follows: It applies only to single equilibrium state. It does not indicate other possible equilibrium in the system. Phase rule consider only the number of phase ,but not their quantities .

What are the limitations of phase diagram?

Phase diagrams only give information on the constitution of alloys, • such as the number of phases present at a point, but do not give infor- mation about the structural distribution of the phases; that is, they do not indicate the size, shape, or distribution of the phases, which affects final mechanical properties.

What is the final pressure in the container of powdered CaCO3?

The data are plotted in the graph below. The student repeated the experiment, but this time the student used a 100.0 g sample of powdered CaCO 3 (s). In this experiment, the final pressure in the container was 1.04 atm, which was the same final pressure as in the first experiment.

How do you calculate the percentage of CaCO3 at equilibrium?

For the reaction: CaCO3 (s) CaO (s) + CO2 (g). Kp = 1 atm at 927^0 C. If 20g of CaCO3 were kept in a 10 liter vessel at 927^0 C, then calculate percentage of CaCO3 remaining at equilibrium:

How many Mol were produced from part(a) of CaCO3?

From part (a) only 0.0115 mol was produced. Hence, the student’s claim was false. Explanation II: The two different experiments (one with 50.0 g of CaCO 3 and one with 100.0 g of CaCO 3 ) reached the same constant, final pressure of 1.04 atm.

What is the equilibrium pressure of CO2 at equilibrium?

Since the measured pressure of CO 2 1 point is earned for correct is also the equilibrium pressure of CO 2 K pexplanation that is consistent = CO 2 P = 1.04 . Note: If the response in part (b) indicates “yes” , that all of the CaCO 3
