Problem

At a certain temperature,

K_P

for dissociation of solid

\text{CaCO}_3

4 \times 10^{-2}

atm and for the reaction,

\text{C}(s) + \text{CO}_2 \rightleftharpoons 2\text{CO}

is 2.0 atm respectively. Calculate the pressure of CO at this temperature when solid C,

\text{CaO}, \text{CaCO}_3

are mixed and allowed to attain equilibrium.
