Second Order & Zero-Order Rate Laws

  • Given Time and Concentration data, if a plot of Reciprocal Concentration (y) vs. Time (x) gives a straight line, then the reaction is 2nd order. The slope of this line is the Rate constant (k) for the reaction.
  • Given Time and Concentration data, if a direct plot of Concentration (y) vs. Time (x) gives a straight line, then the reaction is Zero-Order. The slope of this line is the negative of k, the rate constant.
