At a certain temperature this reaction follows second-order kinetics with a rate constant of 2.2 M^-1s^-1.
2NH3 à N2 + 3H2
Supposes a vessel contain NH3 at a concentration of 0.920 M. calculate how long it takes for the concentration of NH3 to decrease by 92%. You may assume no other reaction is important.
2 significant digits.
Please show me steps.. thank you
