in a reaction,2 NO2(g), <=> N2O4 the rate of disappearance of N2O4 is 2.95 mol/min. What is the rate of disappearance of NO2?

  • science -

    For each mole of N2O4 that disappears, two moles of NO2 are formed.

    2.95 x 2 = ?

    If they really want the rate of DISappearance of NO2, then you have to have a minus sign in front of the answer. Both species cannot be disappearing at the same time.
