Question

For the reaction CaCO3(s) $\rightleftharpoons$­CaO(s) + CO2(g), the value of KP is

Options

A.$P_{CO_{2}}$
B.$\frac{P_{CO_{2}}}{P_{CaCO_{3}}}$
C.$\frac{\lbrack CaO\rbrack\left\lbrack CO_{2} \right\rbrack}{\left\lbrack CaCO_{3} \right\rbrack}$
D.$\frac{P_{CaCO_{3}}}{P_{CaO}P_{CO_{2}}}$

Solution

$K_{p} = \frac{1.P_{CO_{2}}}{1} = P_{CO_{2}}$
