Chapter 12, Problem 70QAP

For the reaction

$\text{C}\left(s\right)+{\text{CO}}_2\left(g\right)\rightleftharpoons 2\text{CO}\left(g\right)$

$K=168$ at 1273 K. If one starts with 0.3 atm of CO₂ and 12.0 g of C at 1273 K, will the equilibrium mixture contain

(a) mostly CO₂?

(b) mostly CO?

(c) roughly equal amounts of CO₂ and CO?

(d) only C?
