Question
True or False. If false, correct to make a true statement.
1. The rate constant for a reaction which follows 2nd order kinetics does not depend on
concentration.
2. The half life of a reaction (for the cases we've studied) is always inversely
proportional to the rate constant.
3. If graphed over time, the concentration of a reactant will be linear for a reaction
which follows first order kinetics.
4. A reaction with a constant half-life of 25 seconds is being studied. There is only one
reactant with an initial concentration of 0.800 M. After 75 seconds, the molarity is
found to be 0.200 M.
