A mixture of 15.0 g CaCO3(s) , 25.0 g CaO(s) , and 0.130 mol of dry ice (solid CO2) is placed in a 10.0 L sealed vessel. After the CO2(s) completely sublimes which of the following statements is true?

the reaction;

CaCO3(s) <---> CaO(s) + CO2(g)

1. When equilibrium is established the mass of CaCO3(s) will be greater than 15.0 g

2. When equilibrium is established the mass of CaO(s) will be greater than 25.0 g

3. There will be no change in the mass of either CaCO3(s) or CaO(s)

4. There is not sufficient information to make a prediction

We will need to know:

Temperature of system, in order to calculate dG and Keq

therefore, we ned more information!
