The decomposition of dinitrogen pentoxide is described by the chemical equation
2 N₂O₅(g) → 4 NO₂(g) + O₂(g) .
If the rate of appearance of O₂ is equal to 3.00 mol min^-1 at a particular moment,what is the rate of disappearance of N₂O₅ at that moment?

Question

Quizplus · Accepted Answer

The stoichiometry of the reaction shows that 2 moles of N2O5 produce 1 mole of O2. Therefore, the rate of disappearance of N2O5 is twice the rate of appearance of O2. Thus, 3.00 mol min^-1 * 2 = 6.00 mol min^-1.
