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


For the reaction above tell whether the reaction would shift to the left (L) or right ® if I

a. Increased the total pressure of the system


b. Removed O2 from the system


c. Increased the amount of NO in the system

  • typo ? -

    Perhaps you mean

    2 NO + O2 --> 2NO2

    3 molecules on left, two on right so if you increase the pressure it will squeeze the reaction to the right more to take up less space.

    If you remove O2, the reaction shifts left because you do not have enough O to combine with the NO and pressure is reduced.

    If you increase NO, you increase pressure and force the reaction right.
