The decomposition of dinitrogen pentoxide is described by the chemical equation
2 N₂O₅(g) → 4 NO₂(g) + O₂(g) .
If the rate of disappearance of N₂O₅ is equal to 1.60 mol min^-1 at a particular moment,what is the rate of appearance of NO₂ at that moment?

Question

According to the balanced equation, for every 2 mol of N₂O₅ that reacts, 4 mol of NO₂ is produced. Therefore, the rate of appearance of NO₂ is twice the rate of disappearance of N₂O₅. Thus, the rate of appearance of NO₂ is 2 x 1.60 mol min^-1 = 3.20 mol min^-1. Therefore, the correct answer is (C).
