Applications Of Equilibrium Constants

Concept: Use equilibrium expression:

Step 1: {Let initial moles of NO and NO = each in 5 L.}

Step 2: {Given [N O] = 0.05 M moles = .}

Step 3: {From stoichiometry, NO and NO consumed = 0.25 moles each.}


Step 4: Substitute into :


Step 5: Solve:
Conclusion:
Required moles = 0.5115
