For the reaction $H_{2(g)} + CO_{2(g)} \rightleftharpoons CO_{(g)} + H_2O_{(g)}$,if the reaction is started with $1 \ mol$ of $H_2$ and $CO_2$ each,and $x \ mol/L$ of $H_2$ is consumed at equilibrium,then the correct expression for $K_p$ will be ........
- A$x^2 / (1-x^2)$
- B$(1+x^2) / (1-x)^2$
- C$x^2 / (1-x)^2$
- D$x^2 / (2+x)^2$
