Concentration Over Time: Integrated Rate Laws and Half-Life

A first-order reaction loses half of what is left in the same time, every time, whether it starts with a ton or a gram. Plot the data three ways and the reaction picks the straight line itself.

in preparation · lesson 21 of 45

By the end

  1. 01Identify the order of a reaction from which plot of concentration versus time is linear
  2. 02Find the rate constant from the slope of the linearized plot
  3. 03Apply the zeroth-, first-, and second-order integrated rate laws
  4. 04Compute a first-order half-life and apply it to radioactive decay
