For the first-order reaction,2 N₂O(g)→ 2 N₂(g)+ O₂(g),what is the concentration of N₂O after 3 half-lives if 0.15 mol of N₂O is initially placed into in a 1.00-L reaction vessel?

Question

Quizplus · Accepted Answer

The reaction follows first-order kinetics, which means that the concentration of N₂O will decrease by a factor of 2 after each half-life. After the first half-life, the concentration of N₂O will be 0.075 M. After the second half-life, the concentration of N₂O will be 0.0375 M. After the third half-life, the concentration of N₂O will be 0.01875 M, which is 1.9 × 10^-2 M rounded to 2 significant figures.
