The decomposition of dinitrogen pentoxide is described by the following chemical equation 2 N₂O₅(g) → 4 NO₂(g) + O₂(g)
If the rate of disappearance of N₂O₅is equal to 1.80 mol/min at a particular moment,what is the rate of appearance of NO₂ at that moment?

Quizplus · Accepted Answer

According to the balanced chemical equation, 2 mol of N₂O₅ produces 4 mol of NO₂ and 1 mol of O₂. Thus, the stoichiometric ratio of the rate of disappearance of N₂O₅ to the rate of appearance of NO₂ is 2:4 or 1:2. Therefore, the rate of appearance of NO₂ is equal to 1.80 mol/min × 2 = 3.60 mol/min. Therefore, the answer is (C).
