First Order Reactions

Rate Laws Concentration [time]. First Order Reactions Goal: convert rate law into a convenient equation to give concentrations as a function of time. For a first order reaction, the rate doubles as the concentration of a reactant doubles. Rate Laws Concentration [time].

In the Binary Collision Model we made a good case for the rate expression:

In the Binary Collision Model we made a good case for the rate expression:. R={ ?(? AB ) 2 < u rel > e -E A /RT } (N A /V)(N B /V). Often, N A /V and N B /V are concentrations in units of molecules per ml. To get these in moles per liter, just multiply by 1000/N 0 !.
