Problem

0.15 mole of CO taken in a 2.5 litre flask is maintained at 750 K alongwith a catalyst so that the following reaction can take place.

\text{CO}(\text{g}) + 2\text{H}_2(\text{g}) \rightleftharpoons \text{CH}_3\text{OH}(\text{g})

Hydrogen is introduced until the total pressure of the system is 8.5 atm at equilibrium and 0.08 mole of methanol is formed. Calculate : (i)

K_P

and

K_C

(ii) The final pressure, if the same mole of CO and

\text{H}_2

as before are used but without catalyst so that the reaction does not take place. (IIT 1993)
