13.59 A reaction of the form aA Products is secondorder with a rate constant of 0.725L/(mols). If the initial concentration of A is 0.760mol/L, what is the molar concentration of A after 88.8s ? 13.60 A reaction of the form aA Products is second order with a rate constant of 0.169L/(mols). If the initial concentration of A is 0.159mol/L, how many seconds would it take for the concentration of A to decrease to 5.50103mol/L
