10. A 1 L container originally holds 0.4 mol of N2, 0.1 mol of O2, and 0.08 mole of NO. If the volume of thecontainer holding the equilibrium mixture of N2, O2, and NO is decreased to 0.5 L without changing thequantities of the gases present, how will their concentrations change?
(A) The concentration of NO will increase； the concentrations of N2 and O2 will decrease.
(B) The concentrations of N2 and O2 will increase； and the concentration of NO will decrease.
(C) The concentrations of N2, O2, and NO will increase.
(D) The concentrations of N2, O2, and NO will decrease.
(E) There will be no change in the concentrations of N2, O2, and NO.
