WebFinal answer Transcribed image text: At a certain temperature this reaction follows second-order kinetics with a rate constant of 20.4M −1 - −1 : 2NH3(g) → N2(g)+ 3H2(g) Suppose a vessel contains NH3 at a concentration of 0.760M. Calculate the concentration of NH3 in the vessel 0.740 seconds later. You may assume no other reaction is important. WebAt a certain temperature this reaction follows first-order kinetics with a rate constant of 0.38 s − 1: ClCH 2 CH 2 Cl (g) → CH 2 CHCl (g) + HCl (g) Suppose a vessel contains ClCH 2 CH 2 Cl at a concentration of 0.500 M. Calculate how long it takes for the concentration of ClCH 2 CH 2 Cl 2 to decrease to 0.025 M.
