initially 0.25 mol of water vapour and 0.20 mor of carbon monoxide are place in a 1.00 L reaction vessel. at equilibrium spectroscopic evidence shows that 0.10 mol of corbon dioxide is present calculate K for the reaction

To calculate the equilibrium constant (K) for a reaction, we need to use the balanced chemical equation. Unfortunately, you have not provided the chemical equation for the reaction involving water vapor (H2O) and carbon monoxide (CO) that leads to the formation of carbon dioxide (CO2).

Please provide the balanced chemical equation, and I will be able to assist you in calculating the equilibrium constant (K) for the reaction.
