Answer: Moles of CO present in the flask are 0.175
Explanation:
Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.
Equilibrium concentration of =
Equilibrium concentration of =
The expression for equilibrium constant for this reaction will be,
Equilibrium concentration of =
Thus moles of CO present in the flask are 0.175
