For the reaction, CaCO 3 (s) CaO (s) + CO 2 (g) , Kp = 0.5 atm at 25 0 C. If 20 gm of CaCO 3 is placed at 25 0 C in a closed container, calculate the amount of CO 2 gas produced when reaction comes to equilibrium. (a) 20 gm (b) 44 gm (c) Data insufficient (d) None of these Please provide complete solution.

Dear Mr. Anurag

For given reaction: Kp=p(CO2);  Cao and CaCo3 are in solid form and so there is not any partial pressure

Kp=nRT/V, but volume of the container is not given so data is not sufficient. Option C is correct.
