CaCO3(s) ⇆ CaO(s) + CO2(g) A 2.00 mol sample of CaCO3(s) is placed in a rigid 100. L reaction vessel from which all the air has been evacuated. The vessel is heated to 898°C at which time the pressure of CO2(g) in the vessel is constant at 1.00 atm , while some CaCO3(s) remains in the vessel. Write the expression for Kp , the equilibrium constant for the reaction, and determine its value at 898°C .

it's filtration, but this is an assumption so my apologies if i got this

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
