Question

1. A mixture of 30.0 mol of NO_(g) and 18.0 mol of O_2(g) is placed in an empty 3.00 liter flask held at a constant temperature. These gases react until the reaction represented below comes to equilibrium. At equilibrium, the vessel contains 26.4 moles of NO₂. What is the value of the equilibrium constant at the constant temperature?

     2NO_(g)     +      O_2(g)    D    2NO_2(g)
