Answer to Question #185564 in General Chemistry for mike

Question

Nitrogen monoxide reacts with oxygen to form nitrogen dioxide.

2NO(g)    +    O2(g)            2NO2(g)

At 1000K the equilibrium constant is 1.60. A mixture of these gases at 1000K contains 0.080mol L-1 oxygen, 0.050mol L-1 nitrogen monoxide and 0.010mol L-1 nitrogen dioxide.

Is this mixture at equilibrium? If not at equilibrium, which direction would the reaction need to shift to achieve equilibrium?

Answer 1

The reaction is not in equilibrium, hence proceeds to the products side
